How would that be different from the ORF? The library as it stands is worse than the ORF: translation into (essentially) tuples hurts error messages; no good story for sum types; no way to make fields strict/unpacked etc.
Hopefully, if this is to become a ghc extension, these problems will be addressed; but then I don't see much difference with the ORF (and thus it wouldn't be any easier to implement).
