Learning Functional Programming in Go

Moses Schonfinkel (1889–1942)

Schonfinkel was a Russian mathematician who invented combinatory logic around 1924. A combinator is a higher order function that uses only function application and earlier defined combinators to define a result from its arguments. This replacement technique reduced multiple function arguments to a single argument, and was later known as currying, after Haskell Curry.

The following table explains Schonfinkel combinators:

Definition	Acroymn - German	Function Type
λx. x	I - Identitatsfunktion	Identity
λx,y. x	K - Konstanzfunktion	Constant
λx,y,z. xz(yz)	S - Verschmelzungsfunktion
