I'm not sure that would make so much sense. From the outside, a  
DynamicArray looks as if it's unbounded in size.  As soon as you  
access element i, the array has size at least i, but normally > i.  So  
the size wouldn't tell you anything about how many elements you  
inserted, or how many are actually intialized, for that matter.  We  
typically use DynamicArray in situations where we either know the size  
outside the array, or where we have to subclass anyway in order to  
remember how many elements are used.

P.S.: I forwarded this to the users list as it might be interesting  
for others, too.
