I wonder if I'm missing something. Couldn't you just remove the entry
from the Lua environment table when the C++ object's destructor is
called?

So, I have this problem with my C++ object binding system. I've
recently added code to store the Lua table that represents my C++
object in the lua registry, with the objects pointer as a key. I did
this so that I can look up the table from the pointer for C++ to Lua
callbacks (i.e. to call a buttons OnClick() method from C++).
However, since I'm storing the lua table in the registry, it is no
longer garbage collected (since it still has a reference)...I had put
the code to remove the reference in the GC method of the object, so
of course it never gets called (DOH).
My question is this: How can I store a reference to my lua object (a
table) without there being an extra reference to it in Lua so it can
be garbage collected?
I'm guessing that there is no official way to store it on the C++ side.
Thanks.
