This code doesn't work!


import std.regex, std.string;

void main()
{
    string baz(RegexMatch!(string) m)
    {
        return std.string.toupper(m.hit);
    }
    auto s = replace!(baz)("Strap a rocket engine on a chicken.",
        regex("[ar]", "g"));
}


RESULT:
    std/regex.d(2840): Error: struct std.regex.RegexMatch!(string).RegexMatch
member test is not accessible

Workaround:
Define the dummy free function for RegexMatch!(string).test.

private bool _dummyTest(Engine)(Engine r, size_t idx)
{
    return r.test(idx);
}


Note:
This issue is maybe related with bug 1904.
- Template function's alias parameter takes delegate.
- Template function uses same module's structs or classes and calls their
private function.
