Comment (by simonpj):

 I'm assuming that much of what Oerjan wants will "just work" once we have
 Richard's kind equalities.  Right Richard?

 But not, perhaps, `kindRep` which I do not fully understand.  I wonder if
 we might address `kindRep` as part of the overhaul sketched in
 [wiki:Typeable this wiki page about Typeable]?  The plan there is to move
 to type-indexed type representations.
  * What would `kindRep` look in that context?
  * How would you use `kindRep`?

 A new subsection on that page might be useful.

 Simon
