Thanks. I didn't realize this double restriction existed.

Since nested Class definitions don't add up that should solve my
problem. Maybe I can stick these useless Combined class definitions at
the end of the file somewhere :) It would be nice if the next version of
the Clean compiler would either complain about it, or handle it
internally.

Great, that helped a lot. Now to try it all out ... .

PS: It would be nice to have these implementation-dependent restrictions
and current outstanding bugs available publicly somewhere.
