I agree with Christian, if you're going to use bounds(), this should be
equal to the number of elements, NOT the number of the last element. So
you would say "3" for 3 elements, even though they're numbered 0..2.
This is the way other similar Perl ops work already:
$size = @a; # 3
$last = $#a; # 2
Having "bounds" be the last index, instead of the max size, is very
counterintuitive. Having "0" mean "1 element" doesn't make any sense.
"0" should mean 0 elements, and -1 should mean the last element.
