Comment (by simonpj):

 OK, so the payload is that you want
 {{{
 typeRepKind : forall (k::*). forall (a::k). TypeRep a -> TypeRep k
 }}}
 At least I think that's the right type.

 That's a nice short specification.  I hope that it would not be too hard
 to implement.

 The whole project of moving from the existing to the new `TypeRep` needs
 someone to lead it; maybe that can be your weekend project!   The key
 ticket is #11011, and wiki page [wiki:Typeable].
