Only namespace would offer that. And may be we need to keep classVar.
Thanks for the question.

BTW:
Character>>initialize
	"Create the table of unique Characters. This code is not shown so that 
the
	user can not destroy the system by trying to recreate the table."
	
How can I see this method....I found that really frustrating.
I tried Character class sourceMethodAt: #initialize but without success.

I have the impression that we would need namespace import.. not so 
simple.
I like your example a lot thanks for this.

they have nothing magic if you do not have pool variables whose value
are computed at compiled time and put in the compiled method (I should 
replay with these to be sure but
in VW it was like that), but only have message send or variable access
then you do not get the problem

I'm trying to see :)
I think that it simplifies: you do not have global variable such as 
Smalltalk, pool and class variable
but just variable in namespaces.

We could do it without namespaces but in such a case you would lose the 
possibility to make a difference
between sharing. Not so simple.
