Hi

I wanted to get feedback about the idea of removing global variables in 
Smalltalk.
The fact that system dictionary or a namespace can contain variable ie 
(a binding to something else than a class)
makes the code quite ugly since we have to always test if this is a 
class or not.

I think that we could easily remove the possibility to have global 
variable and move the ones we have into
classVariable of Smalltalk or appropriate classes. This would lead to a 
more modular system.



Smalltalk keysAndValuesDo: [:k :v | v isBehavior ifFalse: [Transcript 
show: k ; cr]]

Now we would have to type Smalltalk transcript instead of Transcript.

Any thoughts.
