[C++-sig] how to return arbitrary (python-)objects from boost?

A while ago I worked out a proof-of-principle for SWIG-Boost.Python
conversions. The files are here:

http://cctbx.svn.sourceforge.net/viewvc/cctbx/trunk/boost_adaptbx/

  swig_arg.hpp
  swig_args_ext.cpp
  tst_swig_args.py

Also look for "swig" in the SConscript.

I'm guessing something similar could work for SIP, too, but I've never
installed or used SIP.
