I've always considered Unit to just be a nullary tuple. This intuition has never steered me wrong, and it seems that Template Haskell is making the same assumption. If there's some reason that this conflation of ideas is wrong, I would be eager to know -- th-desugar makes this assumption in several places.
Thanks,

I can't answer about "expected behavior", but I can say that those two constructions should be considered identical by the $(…) splice construct. For better or worse, Template Haskell often offers multiple ways of encoding the same source Haskell phrase, and any code that processes Template Haskell syntax should probably treat the two constructs equivalently.
I am not sure I agree that those two constructions should be identical. The Unit type is just a normal type with a single inhabitant: the unit value. How is this related to tuples ?
