This is very efficient; just keep in mind that $thing is actually
aliased to each element of @A in turn, so changing $thing actually
changes @A. Also, *always* (if you can) use this in preference to the C
syntax of
for($i=0;$i<$x;$i++) {}
It's faster and more efficient, doesn't require as many vars, and looks
more Perl-ish. =o)

Just be aware that it's *aliasing*, ~not~ making a copy!
