Rename clashing type variables more consistently
This is minor polishing, but polish is nice:
Consider
:t (id,id,id)
(id,id,id) :: (a -> a, a1 -> a1, a2 -> a2)
this looks as if the first a
is in some way better or more important. What I’d like to see is
:t (id,id,id)
(id,id,id) :: (a1 -> a2, a2 -> a2, a3 -> a3)
In other words: If two type variables clash and need to be renamed, then rename both (all) of them.
