Combine this with an import ... from table statement that creates
locals and I think that you have a killer :-). You get a convenient,
faster access to the globals you need.

import math, table from _ENV as m, tbl

you make the as clause optional, and default on _ENV if the from
clause is omitted.

Assigning to a  naked, undeclared variable would create a local in the
current lexical scope (assuming an identically named upvalue doesn't
exist, of course). You could keep the local statement for declarations
without assignment, and to override upvalues.
