I'll bet you the actual most *common* use of modulus is:
until ( my ($percent_done=done()) == 100 ) { do_work(); print $percent_done,"\n" unless $percent_done % 10; }
And I'll bet it's something like this:
for my $i (0..$#thingies) {
my $css_class = $i % 2 ? 'blue' : 'yellow';
print "<tr class="$css_class"><td>$thingies[$i]</td></tr>\n";
}Pretty useful, actually.
