Absolutely -- as soon as Dr. Stroustrup adds class arguments and
polymorphism to C++.  Until then, the Smalltalk-80* collection classes
(such as Bag, LinkedList, and Dictionary) can't be implemented in C++.
There are other problems, such as Object becomes: (which maybe
shouldn't be in Smalltalk-80, and definitely doesn't fit into the C++
mindset).
