How about passing back a "special" table instead of "table.forward".
This "special" table would be like a forwarding block, waiting for
closure. Attach tag methods to handle:
1) Function call on the "block"
- This would call the proper "forward" function of the original table.
2) Variable get
- Fail? Or perhaps call some unavailable variable handler on the
original table (if available).
3) Variable set
- create the variable in the original table and do the set. Perhaps
informing the table (object) of a variable creation.
... you get the idea...
