Comment:

 This was fixed yesterday. (Dup of #11311).

 In answer to your question: `Void` and `Type` are both (currently) empty
 in terms. But `Void` is also empty in types, whereas `Type` is (obviously)
 not.

 Do not use `Type` as a substitution for `Void`, please, though, as the
 long-term plan includes inhabiting `Type` in terms. After all, `Type` and
 `TypeRep` really should be the same.
