Re: Metatables, C and Script...

Because tables have their own metatables, there's may not be global 
metatable for all tables. Same for full userdata. Dunno about lightweights.

All 'obj:method' calls must pass 'obj' as the first parameter to function, 
no metter what type 'obj' is. So it's extremely wierd if it doesn't. I 
haven't tried this on objects, but it works well with strings and numbers. 
Maybe I couldn't understand what your problem is.

I'm curious about why following does not works:

Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
> t={'a','a'}
> print(t:concat())
stdin:1: attempt to call method 'concat' (a nil value)
stack traceback:
   stdin:1: in main chunk
   [C]: ?

Blessings!
