Words starting with polymorphicla
Maybe these words will be useful:
- polymorphic — polymorphism
- polymorphic function — a function in a computer program that can deal with a number of different types of data
- polymorphic lambda-calculus — (language, types) (Or "second order typed lambda-calculus", "System F", "Lambda-2"). An extension of typed lambda-calculus allowing functions which take types as parameters. E.g. the polymorphic function "twice" may be written: twice = /\ t . \ (f :: t -> t) . \ (x :: t) . f (f x) (where "/\" is an upper case Greek lambda and "(v :: T)" is usually written as v with subscript T). The parameter t will be bound to the type to which twice is applied, e.g.: twice Int takes and returns a function of type Int -> Int. (Actual type arguments are often written in square brackets [ ]). Function twice itself has a higher type: twice :: Delta t . (t -> t) -> (t -> t) (where Delta is an upper case Greek delta). Thus /\ introduces an object which is a function of a type and Delta introduces a type which is a function of a type. Polymorphic lambda-calculus was invented by Jean-Yves Girard in 1971 and independently by John C. Reynolds in 1974.
