--- Comment #4 from Steven Schveighoffer <schveiguy at yahoo.com> ---
opDispatch should be considered before alias this, but apparently it disables
the alias this completely. I thought this would fix the problem but it doesn't:

-------

    auto opDispatch(string name, A...)(A args) if(args.length > 0)
    {
        return mixin("this.coords." ~ name ~ "(args)");
    }

-------

It now simply says there's no property ptr or length for Point. So I think even
though the original bug report was fixed, it wasn't fully fixed.

I think the above should work. As of now, the alias this is completely ignored.
