Right, which is why I suggested that userdata be made into an opaque

interfacing...
Did this really speed up your system or just your benchmarks of how fast you
could push an object from C++ to Lua? After getting slapped around a bit on
the list for doing essentially what you did, I had to admit that push time
wasn't a major factor in most of my profiling however it was implemented.
I am doing a lot of pushing of the C++ instance so Lua can access it. So
yes, this was an accurate test case. I understand that there are
workarounds. But all of them seem very C++ programmer unfriendly and we
are trying to make it easy on C++ programmers to add objects to the
system that are accessible from Lua and vice versa...
