Sorry for being vague and for being flippant too.  By "cheating," I
was specifically referring to violating a basic premise of the Memento
pattern -- which is the state is opaque.  As you have already mentioned,
either the object must persist itself or something external must perform
this operation.

The Memento pattern seems to be a reasonable factoring approach that
minimizes the breaking of encapsulation.  I will either use this approach
or have my list/map class persist itself to/from your io_stream class.

Thanks,
Jason
