Actually (.:) is pretty heavily used to mean:

     (f .: g) x y = f (g x y)

because:

     (.:) = (.) . (.)


A cursory search shows it in:

* 
<http://hackage.haskell.org/package/pointless-fun-1.1.0.1/docs/Data-Function-Pointless.html>

* 
<http://hackage.haskell.org/package/custom-prelude-0.2.2.0/docs/CustomPrelude.html>

and it's probably been defined elsewhere too. I know it shows up on irc 
regularly.
