Comment:
Currently in GHC changing the fixity of a ''term-level operator'', such as
`(+)` also changes the fixity of the corresponding ''type-level
operator''. We could have different fixities for the term-level `(+)`
than the type level `(+)`, but it would be confusing!
So rather than les tyou specify different fixities for each, as your patch
implies, I think it'd be better simply to make `infixr 2 ?` work even when
there is only a type-level `(?)` in scope.
Paolo might you look at this? (It in the renamer, not a big deal I
think.)
