Seeing this old thread[1], I hope something happened towards enabling this.
Does anybody know the current status about using TH on GADTs?

Hi Ozgur,
At least template-haskell-2.4.0.0 (which comes with GHC 6.12) has syntax for
type equality constraints [1], so I'm guessing it should support GADTs (I
haven't actually tested it). It also has syntax for type families.
Cheers,
Pedro
