Re: Golf: ROT-n

Not shorter (yet) but different. Maybe the approach can be improved?

This generates an error on Perl 5.8.4 (Can't modify constant item in postincrement). I thought about a couple of variants of this idea (not this one though) but didn't find a way to get the stroke count low. Particularly not on my version of Perl.	[reply]
