There is no data. It's a pure functional language. The number 1 is a
null-ary function of type Int, which returns value 1.

Therefore, anything you can think of as an operation on data can
obviously be performed on functions - because in Haskell, the only
thing you can *do* is to operate on functions. Values are the things
they return.
