It's not quite the same effect... if I _need_ you to write func's A, B, and 
C, I can with the abstract member functions.  I can't do the same thing 
withprotected constructors.  Your method would necessitate a default 
behaviour on functions where they may not be implementable.  The famous 
"draw()" function of Shape comes to mind.  I don't WANT a default for it!
