I had to fix some breakage caused by this in one of Bryan's libraries.

Some packages (notably `llvm-general-pure`) though, depend on it. Can we add back something like this: {{{ classP :: Name -> [Q Type] -> Q Pred classP cla tys = do tysl <- sequence tys return (foldl' AppT (ConT cla) tysl) }}} and export it again? Or is there such a helper with a different name already?
