It seems opDispatch isn't being used in the with statement. 
That seems like a bug, or maybe a limitation. I'm not sure how 
"with" works, but I assumed it would try calling as a member, 
and then if it doesn't work, try the call normally. Probably 
it's checking to see if it has that member first.

Annoying...

Looks like with statements ignore opDispatch.

struct Foo(int x)
{
    auto opDispatch(string s)()
        if (s == "bar")
    {
        return x++;
    }
}


void main()
{
    int y = 0;
    with(Foo!1)
    {
        y = bar; //error: undefined identifier bar
    }
    assert(y == 2);
}
