in reply to Return a list or an iterator

You may be interested in Damian's talk, "Sufficiently Advanced Technologies", podcast at http://yapc.g.hatena.ne.jp/jkondo/. He mentions some refinements on this technique, such as returning an object with boolean overloads so that while ($iter) {...} will correctly set $_ on each iteration.

[choroba]: Perl to the rescue!
[Corion]: hippo: At least for the German translation, the wordplay is translated as well
[Discipulus]: always! but if i can ask choroba why you always use the inverted (to me) form 1 == $.?
[choroba]: To avoid accidental overwriting of the variable in if ($x = 3)
[karlgoethebier]: Corion: Auch in hessisch? Mer wasses net.
[Corion]: Hmm - I'm not sure, I haven't read the mundart/slang translations ;)
[Eily]: $F[1] =~ s/^0//r could be written as (0+$F[1]). It's less explicit though
