Haskell is claimed to make hard things easy, and impossible things happen. (Though, who knows, perhaps easy things will become impossible with it?)

Not before making easy things hard, though.

You get used to it. The stuff that's easier in other languages than in Haskell is mostly done by hiding distinctions.

Though not completely. Some stuff is made more complicated than necessary because of the choice of syntax. E.g. variadic function in Haskell vs Scheme. Or the the Haskell record-syntax.
