Basically: If you use a variable in string context since it was set (other rules apply, read the perlop manpage for more information), the increment is done as a string. <br> <br> Following these rules, and of course with some creativity, I came up with a way to print my nick "eggzeck"; of course this is for fun, and I'm sharing it for fun/educational purposes. Well, I don't know how much you'll actually learn from this, so it's mostly for fun. <br> <br> Here's what I came up with: <br> <br> <code> <small>$nick = join("", map(++($holder = $_), qw(d f f y d b j)));</small> </code> <br> <br> Pretty cool? The $nick variable will now contain the string "eggzeck".<nobr> <wbr></nobr>:-) eggzeck 2006-10-31T09:29:58+00:00 journal
