slight problem... when I create the user data on the stack
if I pop it off to save it to a table there's no way to push
userdata onto the stack

How would I "peek" into the stack and save the new userdata
without disturbing the values I'm assembling on the stack for
the return?

Thanks for explaining lightuserdata metatables in a clearer manner,
although I have 8 or more types wrapped this is the first time I've
had to return a reference to existing userdata and what a PITA it is!

thanks
Chris
