[C++-sig] A first glance at what could be the boost::python exception system

[David Abrahams]

Berthold,

I'm sorry that I probably don't have time to look at this in detail before
Friday afternoon ends for you; I'll try to get to it over the weekend, and
to respond to your questions in full. It looks good overall. On a stylistic
note I'd like to see more separation of interface from implementation (i.e.
moving member functions outside the function body) and macros (yes, really)
could be used to cut down on code duplication. However, these are minor
details.

Thanks for your contribution,
Dave
