Exception handling

[Tim D. <ti...@ma...>]

I've just been taking a look at pyCxx, and it's looks quite nice.

I notice that in Objects.hxx, there's lot's of code snippets that look
like:
=20
            if (PyErr_Occurred()) throw Exception();

Would it be better to call a function that interrogates the exeception
status, and throws an exception of the appropriate derived type? That
way you could catch more specifically in the C++ code.

Also, is there a reason why Exception doesn't derive from
std::exception?

thanks,
