Obtaining the PyObject * of a class

I'd strongly disagree.
SWIG is very useful for wrapping large scale projects in a
non-interfering manner. If you have to generate bindings for 1000+
classes, it is by far the easiest way to do things.
It isn't clear what you are doing that requires the PyObject*, or which
one you'd like.
In general, the output one is found in $result, and $input is input
PyObject for that typemap.

2 things:

1st. there is a python mailing list for people interested in C++
extension type stuff
2nd. SWIG is useless and overly complicated, its much easier to just
generate your own C++ code by hand, less confusion, and much more
clarity.  I find no value in using anything else.
People complain about the "boilerplate" code, but honestly, copy &
paste, change three characters, and you're done.  And you know exactly
what is happening, how when and why.

	Using Pyrex or Cython is likely to be much easier than using
SWIG for this.
