Hi there,

First off, why are D's regexes called RegExp? Most languages I've come across
use Regex. I know it's only one letter, but I make this mistake a lot.

Second, is there support in the library for non-capturing groups and/or named
groups?

Usually, for a non-capturing group, the syntax is (?:...) instead of the
traditional (...). This is very useful for when you define a group as merely a
set of meaningless sub-options that you don't want to actually match by
themselves.

I tried said format in D, but I got an exception saying: "*+? not allowed in
atom." Is there another way?

Thanks,
--AJG.

I've seen both names used. I just picked one, for better or worse. The api
isn't exactly the same as the regex commonly used in C libraries, so having
a different name is a good idea.

The std.regexp regular expression syntax is as it existed before the
innumerable Perl extensions to it. If you want to add some of them, feel
free to take a whack at std.regexp <g>.
