Comment (by jstolarek):

 Replying to [comment:12 goldfire]:
 > The documentation should make clear that, unlike other constructor
 forms, GADT constructors do ''not'' have the type variables from the
 declaration head in scope.
 Does that make a difference for TH representation (ie. `GadtC` data type)?
