Abstract

We show that call-by-need is observationally equivalent to weak-head needed reduction. The proof of this result uses a semantical argument based on a (non-idempotent) intersection type system called V. Interestingly, system V also allows to syntactically identify all the weak-head needed redexes of a term.
