hash consing

[John S. Yates, Jr.]

Is it possible to implement an "immutable" python
class that maintains a single instance of each unique
value via hash consing?  I know that I can maintain
the hash table outside of the class, lookup the
argument tuple for the class instance I want and only
call the constructor when I the lookup fails.  What
I would really like is to be able to hide that logic
inside the constructor.
