Agreed...

In my opinion, the more useful enhancement to Lua in this
area would be anything like "C" break operator for exiting 
from middle of all loops. "C" like continue is useful too.

The more general decision, I think, would be creating a "pure"
Lua engine. In that case the host program can create multiple
Lua instances (each with its own script running, own global variables
and so on), and can destroy the unneccessary instances.
