Comment:

 Aha, quite right.  Result of an oversight in `TysPrim`.

 This probably is worth merging to 7.10, although some error messages will
 start saying `GHC.Prim.Constraint` instead of `Constraint`.  I've
 addressed that in 547c597112954353cef7157cb0a389bc4f6303eb, but I don't
 think the latter is worth merging.  So just accept the error message
 changes.

 Simon
