It's not too bad. I like it! Haskell uses "$" to do the same thing.

Technically $ means something slightly different, it is more somilar to putting parentheses around the right half of the expression. For function composition it uses the same '.' .

Well, you could use $ in Lisp, too. Thats a standard valid symbol, that doesn't have a builtin meaning.
