Default metatable?

["Peter Loveday" <peter@...>]

I need to be able to provide a default metatable for tables created during 
execution of a script.

I was considering modifying OP_NEWTABLE to set the metatable, but I noticed 
there is a _defaultmeta in the lua_State.  Is there a way I can use this to 
acheive what I want?  If so, how do I set it...

Thanks!

Love, Light and Peace,
