I can remember that long time (say: 30 or more years) ago, I also wrote loops like that.

But now that you mention it, and thinking about it, I notice always write those kind of loops like: 


my $interesting_index= 'not existing';

for ($i=1; $i<=10; ++$i) {
  next unless &condition($i);
  $interesting_index= $i;
  last;
}
# spit an error if $interesting_index is still 'not existing'

The reason behind this is simply that your loop might not have found a valid value.

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e
