要旨:
Modern programming languages offer a lot of guarantees (no or few memory leaks, safe parallel programming, ...). But are they really safe ? The only solution is to formalize them and to prove that the expected properties are fulfilled. That’s why it is relevant to prove essential and general facts about programming languages like those presented in
Types and Programming Languages, a reference book on type systems, in Isabelle/HOL. Isabelle/HOL is a proof assistant, providing type checking and certifying the consistency of proofs. This environment allowed me to discover some imprecision and wrong parts.
