Re: On lua5 and embedding

[Michael Naunton <mmn@...>]

I'd like enlightenment too. I currently just punted and wrote a C++
wrapper template to push userdata as a T*, classTag pair. That way I can
at least allocate my real data in mempools, etc, and vector GC stuff to
the real class. Ugly as hell, but at least the ugliness is contained.
