[erlang-questions] regexp sux!

[Robert Virding]

A few comments about that seeing it is my fault. :-) Anchoring, ^ and $, 
doesn't work when compiling the regexp with compile, but it should work 
when running it directly or with just parse. If it doesn't then it is  bug.

I am working on some new regexp modules with both POSIX and PERL style 
regexps. There will probably be two modules as they don't just have 
different features but also different semantics, they will find 
different matches.

What features are people mainly interested in? What should I focus on to 
start with?

N.B. I am implementing it all in Erlang and not doing an interface to a 
"C" library like PCRE. I mean where's the fun in that?
