Any trick for defining an operator overload in a different namespace?

Right, but this was just a workaround. Anyway I did just realize I can
use opDispatch for this:

-----
class C
{
    this()
    {
        this.opts["foo"] = 1;
    }

    private auto opDispatch(string field : "opts")()
    {
        return this;
    }

    private void opIndexAssign(T)(T value, string option)
    {
        assign(option, value);
    }

    private void assign(string option, int value)
    {
    }
}

It might seem a little funny that the only thing it does is just
returns 'this', which we already had. But I wanted to avoid writing
'this["foo"] = 1;'. Well at the end of the day this may or may not be
what I wanted, since I still want to hide opDispatch. Oh well.. :)
