I prefer $CALLER::_ ("CALLER:: - access caller's lexical variables, then
globals"). I'd expect that you could use the same thing for other
variables, e.g. $CALLER::some_lexical. Of course, the can of worms that
opens is horrifying to consider (and no longer has the benefit of the
ugly caller.MY). :^)

Wire telegraph is a kind of a very, very long cat. You pull his tail in
New York and his head is meowing in Los Angeles. And radio operates
exactly the same way. The only difference is that there is no cat.
