Comment:
It's a bit awkward to exclude this, because we do validity checking on the
type ''after'' converting it to `Type`, at which point the distinction
between `Eq a => Eq b => ty` and `(Eq a, Eq b) => ty` has disappeared.
You are right that it's a bug but I'm not sure it's worth the cycles to
fix it. I'm willing to be told otherwise.
