delegate opCall?

[H. S. Teoh]

>From what I understand from TDPL, given a struct or object obj, writing
obj(x,y,z) will be translated to obj.opCall(x,y,z), correct? So why is
it that this doesn't work:

        struct S {
                RetVal delegate(Args args) opCall;
        }
        void main() {
                auto s = S((Args args) => doSomething(args));
                Args my_args;
                RetVal r = s(my_args);  // this is line 7
        }

I get this error: test.d(7): Error: struct S does not overload ()

An easy workaround is to rename the delegate "impl", then implement
opCall as a wrapper:

        RetVal opCall(Args args) { return impl.args; }

But this seems unnecessarily verbose to me.
