I'm sorry to say that it was entirely unenlightening.  The only  
relevant statement seems to be this "Making a second, independent copy  
of an object is a fairly unusual thing to do in Python, but there  
exist special methods for doing this."  But there is zilch explanation  
of why this is so.  I repeat:  why ever would I want two identical  
objects that _must remain so forever_ ?  I completely fail to grasp  
the utility of this concept.  I cannot think of a single thing that I  
can accomplish with two identical objects that I cannot accomplish  
with only one of them.

Sorry to be so boneheaded about this, but I just don't get it.
