In your example, do "key" and "v.key" refer to the same Lua object, or 
merely to the same C++ object?  That is, did you call a C++ function 
which returned a Lua wrapper for that object, and use that same wrapper 
in both places?  Or did you use two different Lua wrappers, e.g. the 
return values from two different function calls?
