Doesn't it rather strengthen a God class?

There had been different approaches to fan out responsibilities from the Smalltalk global to 
other objects, and different views to consolidate.

Anyhow, given that there are environments now and Smalltalk globals is actually not a SystemDictionary anymore but an Environment,
at lease the access to global names, variables and classes should rather go through globals :)

at least that's my view
