Note that if you redefine (.) composition to be backward application
(flip ($)) then nobody will understand your programs. It's also quite
probably that after reading your own code for a while that you'll not
understand the code that everyone else writes either! :-)

If you want an operator like that, I suggest picking some other symbol.
