--- Comment #3 from Iain Buclaw <ibuclaw at gdcproject dot org> ---
Somewhat simplified reduction of test that doesn't depend on operator
overloading.

struct RegexMatch
{
    string index() { return null; }
    ~this() { }
}
auto m() { return RegexMatch(); }

void initCommands()
{
    auto a = m.index() ~ ' ';
}
