First of all, take note of the syntax of the generic Add<R> method, and also notice that there are

two overloads of Add in MyContainer<T>. Clearly, you need to have a method to add instances of type

T—thus, the need for Add( T ). However, it would be really handy to be able to add an entire range

of objects from another ...
