i don't know what exactly most people need. i'm just pretty sure they 
need a faster implementation than the current one. std.regexp also lacks 
a few fundamental features (like non-greedy matching).
syntax-wise i certainly agree, that one should stick to either the unix 
or perl syntax.
i don't propagate my implementation as a replacement for std.regexp, i 
just wanted to mention it for people who need fast regexps with most 
standard features.
