Element and Holder: A reference counted smart pointer for tagged types where the reference is kept inside the tagged type. This is slightly faster, uses less memory and is more reliable. However it can only be uses for limited tagged types and you need to implement the interface.

Interface Class for Reference Counted Instances Use the interface in when using the base class is not possible. Type for which we want to supply a reference counter. Since, in Ada one can not overload the ":=" operator the type need to be limited so the counter is not damaged by assignment. Mind you, in C++ I almost always make the operator = private in in Reference counted classes as well.
