I have similar problems with stuff like this:

import std.stdio, std.regex;
void main() {
    foreach (m; match("abc", "a|(x)")) {
        foreach (e; m.captures) {
            writeln(e);
        }
    }
}

Here it prints out "a" and then I get a range violation. Whether or not
m.captures[1] exists, iterating over m.captures should be possible?

Also: Checking whether m.captures[1] exists would be highly useful -- to see
what has matched. (Doing this by length wouldn't work in general, of course.)
