Sorry, but the mistake here is the fact that you wrongly assume C 
behavior in C#. Adding chars to an existing string will result in 
a string as in the language specification. The same '+' operator 
works also with multicast delegates and I doubt that you'll 
expect something else than a multicast delegate as a result.
