Hi Quinn,


thanks for commenting.

You misunderstand my problem. There's other state information coded into
class Currency, besides just the value.

I need to couple a given name with a certain instance, not just any instance
of the right 'type'.

Perhaps another example makes it clearer:

c = Currency (30)
c.SetMyState (whatever)

c = Currency (50)

Isn't it true that the second assignment creates a new instance of class
Currency, leaving my former instance with it's state set to whatever, no
longer bound to the name c?

Thanks for the pointers.
