So what are the monks at large opinion on this ever so trivial a subject? Which alternate regex delimiter do you favour? And what are the arguments behind your opinion (if any)?

I prefer []. Except for the RHS with s///e, because I prefer {} there.

[] is VERY easy to read, Data::Dumper B::Deparse uses it a lot and it will make even more sense when we have Perl 6's regexes, where [] is used for grouping.

{} often delimits code. It makes sense with s///e because the RHS is code, and creates scope, etc etc.

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

I escaped the {} to be on the safe side when something is added in front of it in a future version.

Also note that syntax highlighting helps more than choosing the right delimiter.
