[C++-sig] copy_const_reference or return_internal_reference?

[Hugo van der Merwe]

Can things like this go into some documentation somewhere, or maybe a
FAQ? (Wiki?)

It really helps to understand Boost.Python, while I find the current
documentation a little hard to fully comprehend. I suppose once a
tutorial is written, or the documentation finished, things will tend to
be a lot clearer...

Thanks,
Hugo van der Merwe
