[sue]

I haven't had this problem with SWIG/TCL.  Are you sure
python can see the real data from the wrapper, and not just
the data types?  I always put
	typedef { stuff } TYPE; extern TYPE data;
in the .h file I feed to SWIG (unless I use custom accessor
fns).

Both python and tcl will create a variable if they can't
find it, and silently continue on.  This can give you good
separately tested C and python code which fails when you
hook the two together.

Sue.
