   A sequence like this could be a simpler way to introduce curried functions, partial application, and infix operators:

   add5 x = 5 + x
   add5 x = add 5 x
   add5 x = (+) 5 x
   add5 x = 5 `add` x
   add5   = add 5

   I assume the book chose flip and apply as examples because their signatures contain only type variables and no constraints (similar to const, on, compose, etc.), but I'd like to convert to more beginner-friendly alternatives. That change would resolve #260.

   We could even move some of the content from these sections (e.g. Curried Functions and Infix Function Application) to the reference docs (proposed in #282 (comment)). But we'd still want to add exercises (#252) for that material, even if we're just linking to the docs for explanation.
