Perhaps because it makes partial application easier to write.

For example, if I want a vector whose elements are twice the corresponding
elements of x, I can write

	map (fn x => x * 2) x

or, if I have a curried multiply function, I can write

	map (mult 2) x

I suppose I might ask the complementary question: why should compilers
generate slower code for curried functions if I don't happen to make
use of that property?
