The last two commits from (Apr 9) on
<https://github.com/ghc/packages-template-haskell/commits/master/Language/Haskell/TH/Lib.hs>
removed a helper to construct applied type class constraints (`classP`).
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?
Cheers,
Gabor
