in thread Increment by 2 and by 1 in same loop.

It's also possible to define (and initialize, if needed) two (or more) lexical loop variables entirely locally:

for (my ($i, $n) = (1, 2); $i < $limit; $i += 2, ++$n) { do_something_with($i, $n); }

[Eily]: I just wrote a oneliner to solve a (non perl) colleague's problem, and it worked on the first try
[Eily]: and he wasn't impressed
1nickt adds gingersnaps to the platter on the sideboard.
[Eily]: sure it was a pretty standard one liner (of the $h{$1} = $2 if /regex/; END { pp \%h; } variety), but he's not supposed to know that!
[Eily]: what's the point of writing perl if people aren't impressed :P
[sierpinski]: Haha
[Discipulus]: i'm with you!
[Discipulus]: with eskimo greeting is a little bit impressing, anyway
