Thanks! That solves my precise problem.

So, the solution is to do BOTH strategies at once, on the same name:
Define it a C-object, and then *also* as a python object. (at least
semantically.. I haven't looked at the C output) I was only trying
one of those at a time, so I never got it working.

Maybe that should go in the language definition page in the 'tricks'
section. It is a little non-intuitive (but seems logical once you see it).

(oh, and I made a typo in my last email.. 'cdef Module newObj' should be
'cdef MyClass newObj' ..I had renamed it for clarity)
