in reply to counting backward
Because the range operator is defined as low .. high and as 10 is higher than 0, it does nothing.
There are a couple of ways of doing what you want:
- for my $i ( reverse 0 .. 10 ) { print $i }
Which is okay for small ranges; but creates a huge list for large ones.
- for my $i ( -10 .. 0 ) { print -$i }
Which works for any size range without creating a huge list.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
