Since it seems very hard to guarantee the semantics of a local alias are
the same in typical Lua code, the big question is:  are these slightly
different semantics what the user wants?  95% of the time, they probably
are, but ....

I suppose an important adjunct to a Lua compiler would be a way for
program writers to add annotations declaring their intent about such
things (e.g.  common-lisp's "declare" special-form).
