New Revision: 25171

Modified:
   pypy/dist/pypy/rpython/lltypesystem/rclass.py
Log:
two-way wrapping works internally.
That is, we can wrap an instance and produce the real wrapper class.
This works in the test script. Now I"m building it into rclass.py
and change the generated python script.

Funny, lots of internal stuff, but no C code touched at all.
(will probably happen, when I optimize the internal PyCObjects away)
