Paper: Polymorphism is conservative over simple types (Preliminary Report) (at LICS 1987)

Authors: Val Breazu-Tannen Albert R. Meyer

Abstract

We prove that the addition of the Girad-Reynolds polymorphic constructs to arbitrary simply typed equational lambda theories is conservative. This implies that polymorphism can be superimposed on familiar programming languages without changing their behavior.
Using a purely syntactic method , we give an effective proof of conservative extension in the case of equational reasoning that is complete when all types are assumed non-empty. When polymorphic types may be empty, we prove the stronger result that any model of the simply typed lambda calculus can be fully and faithfully embedded in a model of the polymorphic calculus.
