opDispatch shadowing toString - feature or bug?

[Damian Ziemba]

Greetings.

I've been playing around with opDispatch and toString methods and I found 
strange behavior.

Example:

        import std.stdio;

        struct Test
        {
                string opDispatch( string key )()
                {
                        return "I am dispatching in struct!";
                }

                string toString()
                {
                        return "I am Test struct!";
                }
        }

        class Test2
        {
                string opDispatch( string key )()
                {
                        return "I am dispatching in class!";
                }

                string toString()
                {
                        return "I am Test class!";
                }
        }

        void main()
        {
                Test test = Test();
                writeln ( test.s ); // I am dispatching in struct!
                writeln ( test.s() ); // I am dispatching in struct!
                writeln ( test ); // NOTHING :( But should return "I am 
Test struct!"

                Test2 test2 = new Test2();
                writeln ( test2.s ); // I am dispatching in class!
                writeln ( test2.s() ); // I am dispatching in class!
                writeln ( test2 ); // NOTHING :( But should return "I am 
Test class!"
        }

Is it a feature or a bug?
