Comment (by goldfire):

 OK. [wiki:GhcKinds/KindInference wiki page] updated, including type
 synonym CUSKs as described. I still find that a little wonky, but just in
 the concrete syntax, not the semantics.

 For what it's worth, my example in comment:34 does seem to require at
 least one CUSK -- at least, it does in 7.8.

 In any case, I think we're in agreement here about what to do, no?
