Print operator types as infix

Consider the type

{-# OPTIONS -fglasgow-exts #-}
data a :-> b = a :-> b deriving (Show)

Load that file into GHCi and print the type of a simple expression with it.

*Main> :t True :-> False

The actual output will be

True :-> False :: (:->) Bool Bool

Notice that the type constructor has been printed in prefix form. It would be nice if these infix type constructors printed in infix form just like infix data constructors do. For example the desired output would be:

True :-> False :: Bool :-> Bool
