- parametric polymorphism — Polymorphism was first identified by Christopher Strachey in 1967 and developed by Hindley and Milner.

Polymorphic typing allows strong type checking as well as generic functions. ML in 1976 was the first language with polymorphic typing. See also generic type variable.
