--- Comment #1 from Nick Treleaven <nick@geany.org> ---
Is a function allowed to return an `enum string`? Shouldn't you use one of these:

string b(alias d)() {
    return `writeln("a");`;
}

enum string b(alias d) = `writeln("a");`;

I think this should be marked `accepts-invalid`.

Also you should use a string mixin, `mixin(b!a);` - not a template mixin.

I think mixing in an eponymous template should be an error as it is confusing. Reduced:

void main() {
    template b(alias d) {
        enum b = ``;
    }

    int a;

    {
        pragma(msg, is(typeof(b) == string)); // false
        mixin b!a;
        pragma(msg, is(typeof(b) == string)); // true
        mixin b!a; // error
    }
}

As before, if the {} scope block braces are removed, there's no error.
