Re: Bind Variables?

["Peter Cawley" <lua@...>]

If you want to do this, and make it feel natural to Lua, then it is a
bit of a pig to do: Create a table (T), assign it a fresh metatable
(MT), add an __index metamethod to MT which reads the value from the C
structure and then add a __newindex metatable to MT which writes the
value to the C structure.
