Late to the party but I love regexes.<br>
<br>
Patrick's /[^\w\W]/ made me think of /[\d\D]/ or /[\s\S]/ or any character class containing complementary subsets<br>
<br>
My own invention is /^^/ or /$$/ or any match which can only occur once occuring twice<br>
</blockquote><div><br>Neither of these works for the intended purpose.<br><br>/^^/ always matches, which stands to reason, since after you match the front, you're still at the front. <br><br>$$ is an interpolated scalar variable.<br>
<br> print "match" if $$ =~ /$$/; # prints "match"<br><br>Also, even though $$ is readonly, I could easily use Inline::C or some XS code to allow me to do this:<br><br> $$ = ""; $anything =~ /$$/;<br>

Still, my vote goes to Ingy's /.^/ because not only does it use the least characters (at least I havn't seen any single character candidate), but it also uses the least ink :)<br>
