I was just going to extend it for my project when I eventually get around to it, probably not for another few months (I want to see Descent get as strong an IDE as JDT before I start splitting my attention). If you think it might be useful for scregexp, I don't think it'd be too hard to add.

Thinking a bit more about it, an array might be better for that. _[0] would be the first capture, _[1] the second, etc. But that still doesn't allow something awesome like:

if(str =~ m/(\d+)_(\w+)/)
{
    print "$1 = $2";
}

... or how I'd like to see it in D:

if(str.matches(`(\d+)_(\w+)`)
{
    writefln("%d = %d", _[0], _[1]);
}

... where matches() compiles the regex at compile time like scregex.

Oh well, maybe AST macros will open up that possibility, though I'm not sure exactly how that's work.
