Hello, I'm trying to make a regex comparison with D, based off of this article: https://swtch.com/~rsc/regexp/regexp1.html

I've written my code like so:

import std.stdio, std.regex;

void main(string argv[]) {

        string m = argv[1];
auto p = ctRegex!("a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
        if (match(m, p)) {
                writeln("match");
        } else {
                writeln("no match");
        }

}

And the compiler goes into swap. Doing it at runtime is no better. I was under the impression that this particular regex was used for showcasing the Thompson NFA which D claims to be using.

The golang code version of this runs fine, which makes me think that maybe D isn't using the correct regex engine for this particular regex. Or perhaps I'm using this wrong?
