Henrik, not Henryk. And I would probably say Dan's/Henrik's Environments
- Dan started that path and Henrik tried to fulfil it.

Personally I think it is too complicated - I dislike hierarchies in
general :). But yes, the idea was to use late binding using message
sends etc.

In fact, using my Namespaces you can do both I guess. We could implement
a DNU on class Namespace and that would be it. They are already reified
globals hanging in Smalltalk under their own name.

And right, I started on that Detailed walktrough I promised - but I only
got through the "core" part and actually found an issue and also need to
study some parts of it more to get it all nailed down. If you file that
core part into say a 3.7 image the idea was that you could then create
classes like Foo::Bar and use them (and thus be able to file in new code
written with these namespaces). But the method #scopeVariable needs to
be different for this to work - it expects to find an instance of
Namespace called #Foo in Smalltalk - which of course will not be there.

But here is the current draft:
