Not enough coffee this morning, I guess, but the point was to
illustrate, not give working code. I think OP got it.

I suppose it's an alternative, but why replace a constant with a
variable if you don't have to? The only reason to do that would be if
you messed with $[. Don't do that. Ever. Ever ever. At least not in
any situation that's likely to get discussed on a beginners' list.

That's not really an alternative, because $_ is populated with the
value of the current element of @ary. In the original example, it's
populated with an integer. cf:
my @array = qw/a b c d e f/;
print "$_\n" for 0..$#array;
print "$_\n" for @array;
print "index $_ is $array[$_]\n" for 0..$#array;
print "index $_ is $array[$_]\n" for @array;
Have fun with that last one. Again, the point was to illustrate where
$#array might be useful, not to play golf.
