Well, many things may bring the same results. :) The C-Style Loop also allows to do something like this: 
for($i = $#sizes; $i >= 0 ; --$i)
{
    print $sizes[$i];
}

I haven't tested it yet whether this also works:
for my $i ($#$arrayref .. 0)

And you can also do this: 
for(my $i = 0; $i <= #$arrayref; $i+=2)
{
 print "$i: $arrayref->[$i]\n";
}

Yes, you could do instead: 
for my $i (0 .. $#$arrayref)
{
    print "$i: $arrayref->[$i]\n";
    $i++;
}

But here you have to be aware that $i is incremented by 1 by the loop itself and then again by 1 through $i++. Makes it a bit more difficult to read imho.
I guess in the end it's what you prefer. :)
