Abstract

It is well-known that the type system of ML is overly restrictive in its handling of recursion: certain intuitively sound emphterms do not pass ML's type-check. We formalise this intuition and show that the restriction is semantical: there are computable (semantical) emphfunctions which cannot be expressed by well-typed (syntactical) terms.
