Region analysis and the polymorphic lambda calculus

We show how to translate the region calculus of M. Tofte and J.P. Talpin (1997), a typed lambda calculus that can statically delimit the lifetimes of objects, into an extension of the polymorphic lambda calculus called F/sub #/. We give a denotational semantics of F/sub #/, and use it to give a simple and abstract proof of the correctness of memory deallocation.
