A newbie question:

I've defined 2 classes with a poolDictionary ('P') (Squeak created 
the poolDictionary for me).  I referenced/added to the dictionary 
in the class methods.  But it appears that ANY class can now 
reference 'P' without including it in the class definition!

Is 'P' global?

What's the value in placing 'P' in a class definition if it's 
global and can be accessed with or without including in the class 
definition?

How do I view the defined poolDictionaries?

Where can I get a first class explanation of poolDictionaries 
(their uses)?
