The last missing feature of ctRegex compared to regex.

For example the following test should pass.

import std.algorithm, std.regex;

void main()
{
    auto cr = ctRegex!(`(?<=(ab))\d`);
    auto m = match("12ba3ab4", cr); 
    assert(m);
    assert(m.hit == "4");
}

Andrei, it would be helpful if you could please comment on why these seemingly
normal bugs are blockers.

Interesting.  You could also add the 'industry' keyword to these issues to
raise their profile.
