[C++-sig] Ping: Howto expose exception classes using boost.python?

[Alex Mohr]

The way I solved it was to actually implement an exception class in 
python (that derived from RuntimeError) and then call into my wrapped 
module, passing that class object.

I store the class object in my C++ code, and then when I want to make an 
exception, I just invoke the class object's operator(), set the python 
exception state to that class/instance, and throw_error_already_set().

It would be lovely if boost python let you create extensions classes 
that derived from python classes, but I'm not sure what this would entail.
