WebFeb 2, 2013 · The practical answer is that currying makes creating anonymous functions much easier. Even with a minimal lambda syntax, it's something of a win; compare: map (add 1) [1..10] map (\ x -> add 1 x) [1..10] If you have an ugly lambda syntax, it's even worse. (I'm looking at you, JavaScript, Scheme and Python.) WebHow currying is applied •Note the type of pow: - fun pow x 0 = 1 = pow x y = x * pow x (y - 1); val pow= fn : int -> int -> int What does this type mean? •Every application of curried functions is a composition: pow 2 10 creates an intermediate function (pow 2) and calls it, passing it the argument 10
