Missing support for the new qualified operator syntax

[nibro]

Haskell' (whatever form it will come in) will likely have a different form of qualified operator syntax from Haskell98.

  add x y = Prelude.(+) x y
  subtract y = (`Prelude.(-)` y)

Not that it matters, but I find this new syntax far preferable to Haskell98.

I doubt there are many (if any) programs that use this already, so the priority is quite low. It will be done eventually though.
