When Does Point-Free Notation Make Code More Readable?

Using even better (PureScript) syntax, the pointfree version of the latter can be written in notation similar to a hom-functor.

   f1 = pow 2
   f2 = pow _ 2

This makes it look like a lambda but without having to bind an argument explicitly. Makes it much nicer to write complicated expressions (although I can't speak to the readability for people less fluent in the syntax).

You still have to remember that pow has 2 args, and not 1 or 3, to get a basic sense of what kind of object f1 is. How about:

   f1 x = pow 2 x
   f2 x = pow x 2

Kind of irrelevant in a language that has type declarations on the previous line.
