True, but to define the __exit__ method you need to write a C++ method
with the following signature

void func(boost::python::object exc_type,
          boost::python::object exc_val,
          boost::python::object exc_tb)

Most of the C++ objects I wrap are not python aware. I'd like some way
of wrapping a call to a simple method (e.g. void cleanup()). I suppose
I'm looking for a generic way to discard arguements from python.
