Heh, for some reason it's the standard name used for the lua_State pointer.

Ah ok.

I've started some work on the registry. Basically I have made templates
from the registry code and started on the central registry. I've organized 
it like
this:

   boost/langbinding/registry.hpp
   boost/langbinding/impl/registry.hpp

The implementation files are to be included in cpp files for luabind/bpl where
the templates they contain are explicitly instantiated.

Shall I check this in?

BTW. I noticed that my replies are out of thread on gmane, if anyone has any
idea on what I can do to fix this I'd be grateful.
