Fixity declaration for associated type rejected
When I say
{-# LANGUAGE TypeOperators, TypeFamilies #-}
module Bug where
class C a where
type a # b
infix 4 #
I get
Bug.hs:7:11: ‘#’ is not a (visible) method of class ‘C’
But it really should just assign a fixity to the type #
. It works if the fixity declaration is outside of the class.
