Nice that you++ picked up the off by one which exactly illustrates the problem with C for loops. I don't much like the while loop solutions because they don't make the number of iterations clear, particularly in conjunction with the post decrement operator - that's just far too subtle.

Actually, to get the count right and clear I'd:

for (1 .. $count + 1) {

[download]

If the values are required I'd:

for my $value (reverse 0 .. $count) {

[download]

which makes it very clear that the values are required in reverse order and the span of values required, but obfuscates the number of iterations somewhat.

True laziness is hard work
