Infix typeconstructors shown as prefix

[Remi Turk]

Hi,

with the following definitions

{-# OPTIONS -fglasgow-exts #-}
data a :++: b
class a :--: b

ghci prints the infix type(classe)s as prefix:

*Main> :i :++:
data :++: a b 	-- Defined at foo.hs:2:7

*Main> :i :--:
class :--: a b where 	-- Defined at foo.hs:3:8

or (a "real-world" example):

*Main> :t fac (One:@Zero:@Zero)
fac (One:@Zero:@Zero) :: :@ (:@ (:@ (:@ One One) Zero) Zero) Zero

Is this a bug, a feature or just Not Implemented Yet(TM)?

Groeten,
Remi

P.S. Are infix class-names a documented extension at all?
