Formalisation et implémentation de techniques sûres pour la programmation par passage de destination dans les contextes fonctionnels purs

Destination-passing style programming introduces destinations, which represent the address of a write-once memory cell. These destinations can be passed as function parameters, allowing the caller to control memory management: the callee simply fills the cell instead of allocating space for a return value. While typically used in systems programming, destination passing also has applications in pure functional programming, where it enables programs that were previously unexpressible using usual immutable data structures. In this thesis, we develop a core λ-calculus with destinations, λd. Our new calculus is more expressive than similar existing systems, with destination passing designed to be as flexible as possible. This is achieved through a modal type system combining linear types with a system of ages to manage scopes, in order to make destination-passing safe. Type safety of our core calculus was proved formally with the Coq proof assistant. Then, we see how this core calculus can be adapted into an existing pure functional language, Haskell, whose type system is less powerful than our custom theoretical one. Retaining safety comes at the cost of removing some flexibility in the handling of destinations. We later refine the implementation to recover much of this flexibility, at the cost of increased user complexity. The prototype implementation in Haskell shows encouraging results for adopting destination-passing style programming when traversing or mapping over large data structures such as lists or data trees.
