what is so great about "currying"? What are its uses, apart from letting one define functions with less parentheses?

it's just really handy. It saves you a lot of tedious typing
I agree. But I think there is more to it than that. Currying is more than just a way to make it easier to convert a function into a different function with a different number of parameters. The original function is *already* a function of any number of its parameters that you want, all at once. That way of thinking gives you a lot of power, while preserving compile-time type safety and crystal-clear readability. I think this is one of the ingredients that contribute to the gestalt "wow" feeling that many beginners experience when they first "get it" in Haskell - a sudden exhilarating, liberating feeling of expressiveness.
