Comment (by goldfire):

 If that was ever accepted without `-XTypeOperators`, regardless of
 `-XStarIsType`, it's a bug. After all, you are quoting a type operator.
 Note, however, that `-XStarIsType` is on by default, and therefore `*` is
 not considered an infix operator in types (by default). So it's as if you
 wrote `''(Type)`, which indeed is an error.
