Neat trick Steve.

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...
