Interesting, for sure. I've always favored the pithier version of:
for my $count (0..2) {
my $s = (1 == $count)? "": "s";
print "$count iteration$s so far...\n";
}
Of course, it's gotta be tweaked under certain circumstances:
for my $cheese_eaters (0..2) {
my $noun = (1 == $count)? "mouse": "mice";
print "$cheese_eaters $noun so far...\n";
}
By the way, the (<constant> == $count) is a habit I picked up from a company which had some good ideas about coding guidelines. (It was for C, but applies to Perl as well). The idea is that you can never accidentally write '=' instead of '==' because the compiler will detect an attempt to assign to a constant and forbid it outright.
