Re: Extending C++ classes under Lua

[Don Hopkins <dhopkins@...>]

How does the "__getitem" and "__setitem" magic stuff in 
SWIG_Lua_class_get and SWIG_Lua_class_set work?

It delegates to a function in the metatable called __getitem and 
__setitem, but I'm not sure how to set these up, or get a reference to 
the metatable from lua to poke my function in there.

I think the __getitem hook would be useful to delegate unknown 
attributes to a lua peer object (stored in the environment of the 
userdata).
