  abstract = {ML modules are offer large-scale notions of composition and
                  modularity. Provided as an additional layer on top of the
                  core language, they have proven both vital to the working
                  OCaml and SML programmers, and inspiring to other
                  use-cases and languages. Unfortunately, their
                  meta-theory remains difficult to comprehend, requiring
                  heavy machinery to prove their soundness. Building on a
                  previous translation from ML modules to Fω, we propose a
                  new comprehensive description of a generative subset of
                  OCaml modules, embarking on a journey right from the
                  source OCaml module system, up to Fω , and back.  We pause
                  in the middle to uncover a system, called canonical that
                  combines the best of both worlds. On the way, we obtain
                  type soundness, but also and more importantly, a deeper
                  insight into the signature avoidance problem, along with
                  ways to improve both the OCaml language and its
                  typechecking algorithm. }

                  of type features including type containment, bounded and
                  instance-bounded polymorphism, as well as subtyping
                  constraints as used for ML-style type inference with
                  subtyping.  Type soundness is proved by adapting the
                  step-indexed semantics technique to strong reduction
                  strategies, moving indices inside terms so as to control
                  the reduction steps internally.  },

                  considered well-understood, adding them to a language with
                  a notion of subtyping comes with a few surprises. What
                  does it mean for a GADT parameter to be covariant?  % The
                  answer turns out to be quite subtle and involves
                  fine-grained properties of the subtyping relation that
                  raise interesting design questions.  % We allow variance
                  annotations in GADT definitions, study their soundness,
                  and present a sound and complete algorithm to check them.
                  Our work may be applied to real-world ML-like languages
                  with explicit subtyping such as OCaml, or to languages

                  usual algebraic datatypes with a form of dependent typing
                  that has many useful applications, but raises serious
                  issues for type inference. Pattern matching on GADTs
                  introduces type equalities with limited scopes, which are
                  a source of ambiguities that may destroy principal
                  types---and must be resolved by type annotations.  By
                  tracing ambiguities in types, we may tighten the
                  definition of ambiguities and confine them, so as to
                  request fewer type annotations.  Now in use in OCaml 4.00,
                  this solution also lifts some restriction on object types

                  retyping functions, are well-typed eta-expansions of the
                  identity. {T}hey may change the type of terms without
                  changing their behavior and can thus be erased before
                  reduction.  Coercions in {F}-eta can model subtyping of
                  known types and some displacement of quantifiers, but not
                  subtyping assumptions nor certain form of delayed type
                  instantiation. We generalize F-eta by allowing abstraction
                  over retyping functions. We follow a general approach
                  where computing with coercions can be seen as computing in
                  the lambda-calculus but keeping track of which parts of
                  terms are coercions. We obtain a language where coercions
                  do not contribute to the reduction but may block it and
                  are thus not erasable. We recover erasable coercions by
                  choosing a weak reduction strategy and restricting
                  coercion abstraction to value-forms or by restricting
                  abstraction to coercions that are polymorphic in their
                  domain or codomain. The latter variant subsumes {F}-eta,
                  {F}-sub, and {MLF} in a unified framework.},

                  ML and of several extensions starting from small

                  obtain a type system for a language with record
                  concatenation by composing the translation with
                  typechecking in a language with record extension.  We
                  apply this method to a version of ML with record extension

                  symmetric concatenation.  The latter extension is simple,
                  flexible and has a very efficient type inference algorithm
                  in practice.  Concatenation together with removal of
                  fields needs one more construct than extension of records.
                  It can be added to the version of ML with record
                  extension.  However, many typed languages with record

                  introduction and elimination of existential types into
                  more atomic constructs. Open existential types model
                  modular type abstraction as done in module systems. The
                  static semantics of Fzip adapts standard techniques to
                  deal with linearity of typing contexts, its dynamic
                  semantics is a small-step reduction semantics that
                  performs extrusion of type abstraction as needed during
                  reduction, and the two are related by subject reduction
                  and progress lemmas. Applying the Curry-Howard
                  isomorphism, Fzip can be also read back as a logic with
                  the same expressive power as second-order logic but with
                  more modular ways of assembling partial proofs. We also
                  extend the core calculus to handle the double vision
                  problem as well as type-level and term-level
                  recursion. The resulting language turns out to be a new

  abstract = { In the last five years there have been many proposals for
                  adding records in strongly typed functional languages.  It
                  is agreed that powerful operations should be provided.
                  However the operations are numerous, and there is no
                  agreement yet on which ones are really needed, and what
                  they should do.  Moreover, there is no basic calculus in
                  which these operations can be described very easily.  We
                  propose a projective lambda calculus as the basis for
                  operations on records.  Projections operate on elevations,
                  that is, records with defaults.  This calculus extends
                  lambda calculus while keeping its essential properties.
                  We build projective ML from this calculus by adding the ML
                  Let typing rule to the simply typed projective calculus.
                  We show that projective ML possesses the subject reduction
                  property, which means that well-typed programs can be
                  reduced safely.  Elevations are practical data structures
                  that can be compiled efficiently.  Moreover, standard
                  records are definable in terms of projections.  },

  abstract = {{E}rasable coercions in {S}ystem {F}-eta, also known as
                  retyping functions, are well-typed eta-expansions of the
                  identity. {T}hey may change the type of terms without
                  changing their behavior and can thus be erased before
                  reduction.  Coercions in {F}-eta can model subtyping of
                  known types and some displacement of quantifiers, but not
                  subtyping assumptions nor certain form of delayed type
                  instantiation. We generalize F-eta by allowing abstraction
                  over retyping functions. We follow a general approach
                  where computing with coercions can be seen as computing in
                  the lambda-calculus but keeping track of which parts of
                  terms are coercions. We obtain a language where coercions
                  do not contribute to the reduction but may block it and
                  are thus not erasable. We recover erasable coercions by
                  choosing a weak reduction strategy and restricting
                  coercion abstraction to value-forms or by restricting
                  abstraction to coercions that are polymorphic in their
                  domain or codomain. The latter variant subsumes {F}-eta,
                  {F}-sub, and {MLF} in a unified framework.},

                  small-step reduction semantics that enjoys the subject
                  reduction property.  Traditional closed existential types

  abstract = {The language MLF has been proposed as an alternative to
                  System F that permits partial type inference a la ML.  It
                  differs from System F by its types and type-instance
                  relation. Unfortunately, the definition of type instance
                  is only syntactic, and not underpined by some underlying
                  semantics. It has so far only been justified a posteriori
                  by the type soundness result.  In this work, we revisit
                  MLF following a more progressive approach stepping on
                  System F.  We argue that System F is not a well-suited
                  language for ML-style type inference because it fails to
                  factorize some closely related typing derivations. We
                  solve this problem in Curry's style MLF by enriching types
                  with a new form of quantification that may represent a
                  whole collection of System F types.  This permits a
                  natural interpretation of MLF types as sets of System-F
                  types and pulling back the instance relation from set
                  inclusion on the interpretations. We also give an
                  equivalent syntactic definition of the type-instance,
                  presented as a set of inference rules.  We derive a
                  Church's style version of MLF by further refining types so
                  as to distinguish between user-provided and inferred type
                  information.  The resulting language is more canonical
                  than the one originally proposed. We show an embedding of
                  ML in MLF and an encoding of System F into MLF.  Besides,
                  as MLF is more expressive than System F, an encoding of
                  MLF is given towards an extension of System F with local
                  binders.}

                  non-atomic-subtyping based on constrained types for
                  first-order lambda-calculus (no Let) with one-field
                  records given with a call-by-value reduction semantics.
                  We then extend the language with general records with
                  concatenation.  This case study shows the flexibility of
                  type inference with constrained types.  We extend the
                  constrained types with type operators in order to
                  type-check record concatenation in the presence of
                  subtyping.  This method should provide wrappers to
                  object-oriented languages based on the
                  objects-as-records-of-methods paradigm.  We do not address
                  the practical issues of type inference here.  },

  abstract = { We analyze the way in which a result concerning the
                  absence of runtime type errors can be expressed when the
                  semantics of a language is described using proof rules in
                  what is sometimes called a natural semantics. We argue
                  that the usual way of expressing such results has
                  conceptual short-comings when compared with similar
                  results for other methods of describing semantics. These
                  short-comings are addressed through a form of operational
                  semantics based on proof rules in what we call a partial
                  proof semantics. A partial proof semantics represents
                  steps of evaluation using proofs with logic variables and
                  subgoals. Such a semantics allows a proof-theoretic
                  expression of the absence of runtime type errors that
                  addresses the problems with such results for natural
                  semantics. We demonstrate that there is a close
                  correspondence between partial proof semantics and a form
                  of structural operational semantics that uses a grammar to
                  describe evaluation contexts and rules for the evaluation
                  of redexes that may appear in such contexts. Indeed,
                  partial proof semantics can be seen as an intermediary
                  between such a description and one using natural
                  semantics. Our study is based on a case treatment for a
                  language called RAVL for Records And Variants Language,
                  which has a polymorphic type system that supports flexible
                  programming with records and variants.  },

                  principal typings and subject reduction. A new set of
                  typing rules is proposed so that type generalization is
                  simpler and more efficient. We consider typing problems as
                  general unification problems, which we solve with a
                  formalism of unificands. Unificands naturally deal with
                  sharing between types and lead to a more efficient type
                  inference algorithm. The use of unificands also simplifies
                  the proof of correctness of the algorithm by splitting it

  abstract = { Many type systems for records have been proposed. For
                  most of them, the types cannot be described as the terms
                  of an algebra. In this case, type checking, or type
                  inference in the case of first order type systems, cannot
                  be derived from existing algorithms. We define record
                  terms as the terms of an equational algebra. We prove
                  decidability of the unification problem for records terms
                  by showing that its equational theory is syntactic. We
                  derive a complete algorithm and prove its termination. We
                  define a notion of canonical terms and approximations of
                  record terms by canonical terms, and show that
                  approximations commute with unification. We also study
                  generic record terms, which extend record terms to model a
                  form of sharing between terms. We prove the syntacticness
                  of the equational theory of generic record terms and the
