This version certainly seems to work, but is it lazy, crazy, peevish, peccant, or...?

I think it's the version I would choose if I hated the person who would be maintaining my code!

Update: ++ for the whole reply for diversity and perversity!

Feel free to replace the semicolons (except the last) with xors for even more perversity.	[reply]

++ and amen, but only with `no warnings 'void';` since one cannot enjoy perversity incautiously. In fact, wouldn't any of the left-associative operators `* x + - . << >> & \| ^ , => xor` do as well so long as precedence levels were not mixed unwisely? Although I haven't thoroughly tested it, I like: `>perl -wMstrict -le "$_ = 'p1r4k/8'; my $t = 'p-r----k/--------'; no warnings 'void'; s/8/7-/g-+s/7/33-/g-+s/6/5-/g-+s/5/22-/g-+s/4/3-/g-+s/3/11-/g-+s/2/1- +/g-+s/1/-/g; print qq{'$_'}; print $_ eq $t; " 'p-r----k/--------' 1` [download]	[reply] [d/l] [select]
