I don't like this.  I see writability as orthogonal.  I'm sure there's good uses for read-only globals that are not classes.  I like the tenseness though.  So

    Smalltalk globals declarations reject: #isClassBinding

with
isClassBinding ^value isBehavior and: [key == value name]

Forgive me; I missed a not in there.  But my point is that the classes in global are in bindings whose keys are == to their name.  Everything else is a global variable.

Is there a definition in text somewhere?  Colin?
