I think we should get the nestmate stuff nailed down first, then we can see more clearly how to do the U.DC nest injection logic.  The existing, rather random stuff host-access logic will be hard to specify, and will be subsumed (and outdated) by nestmates.

The isolated method idea can be specified "as if" there were a class wrapped around the method, but discarded.  The specification burden for that, probably, is defining what MethodHandleInfo (if any) comes out of cracking the MH for the isolated method.  "No info" is a good starting point.

Remi's idea of an ad hoc "get my user data" API point (in Lookup for safety) makes sense to me; I don't see how to improve it.
