/// A BasicEvent uses internally a DefaultStrategy which
/// invokes delegates in an arbitrary manner.
/// Note that one object can only register one method to a BasicEvent.
/// Subsequent registrations will overwrite the existing delegate.
/// For example:
/// BasicEvent<int> event;
/// MyClass myObject;
/// event += delegate(&myObject, &MyClass::myMethod1);
/// event += delegate(&myObject, &MyClass::myMethod2);
///
/// The second registration will overwrite the first one. The reason is simply that
/// function pointers can only be compared by equality but not by lower than.
