Instead of cloning a table A into a table B, why not create an empty table B
and set the __index metamethod of B to be A? With this setup, reading from B
reads from A, but writing to B writes to B, not to A. To handle tables inside A,
the __index metamethod would have to set the same scheme for these tables.
