Look at chapter 4 of the lua reference manual.

I think you can get/set upvalues of a c closure, but you can't get/set
locals of a lua closure (if its not currently active).

Even once you access the upvalue, duplicating it is not so easy in the
general case, you might have to do a deep copy of a table.
