Yeah.  I really see your point.  I'm just uncomfortable breaking 
people's code too much.  A sub-class is a good idea.   It's a good place 
to experiment with new ideas.  It's one of the reasons we wanted the 
array to be sub-classable. 

Making a sub-class a super-class is also possible once it's working.
