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.)
