Because GADTs cannot represent record constructors. I didn't make GadtC
a constructor for Con as I don't think you could pretty-print a
datatype with both GADT and record constructors.

Also, TH tries to present the completely sugared language to the user;
otherwise it would probably work on something more like core.
