in reply to Whats your favorite nonstandard regex quote char?

It all depends on what I'm doing... If it's a script that I'll use more than once, I tend to lean towards readability. If it's an obfuscation, I go for confusion of course.

For what should be obvious reasons, these are some of my personal favorites:
s@{.*?}@{$sub[$n++]}@g;
s${.*?}${$sub[$n++]}$g;
s%{.*?}%{$sub[$n++]}%g;
s={.*?}={$sub[$n++]}=g;

    For shame! Where is 

    s;{.*?};{$sub[$n++]};g;

      's' is a fun delimiter, especially with a /s modifier and some variables named 's' for good measure. :) 
      ss{.*?}s{$s[$s++]}ss;

        Might not be appreciated so much over here in Germany though...

    Yes I can see those being favorites for obfuscation - in general work its likely better to avoid the use of overly meaningful characters. I'd include sigils at the top of that list, then other things that are likely to confuse (like the pound character). I waver between the various bracketed characters - curly braces, square braces, chevrons and in last place parentheses. Which one I actually use is predicated on what the content of the expression is and whether it conflicts with my delimiters.

      Naturally. But assuming that the only character that is out of bounds is the / which would you use and why?
