Hi,
@normal = (0,1,2,3,4,5,6,7,8,9);
foreach (0..$#normal) { unshift @reverse, (shift @normal) };
this also works fine.

Objet: reverse range (10..1)
Is there any (quick and easy) way to get a reverse range, like (10..1),
rather than a standard (1..10)? The catch is to *not* use 'reverse'.
I'm teaching Sun's perl course this week (DTP-250), and we were talking
about working on arrays. The book had an exercise that had the student
reverse an array by using pop (or shift, I don't remember). That section is
before we talk about 'reverse', and I thought you'd be able to do it like:
@array[0 .. $#array] = @array[$#array .. 0]
...but of course, having the range count down doesn't work.
