I don't agree. I wanted it to be a single level by design. Simple.
Buckets of names. And I don't want them to be fine granular - they
aren't Categories - they are Namespaces. One per Project is well enough.
One for basic official Squeak is just fine - and in that particular case
we just use good ole Smalltalk.

And as I wrote in some other post - what does the hierarchy really mean?

Right! I did the exact same thing you know. :)

Ok. So then you would be using imports purely for constraining lookup.
Could easily be added of course.
Btw, the core of my solution is now described in perfect detail (and I
just tweaked it so that it seems to work in 3.9):

As I said - for basic official Squeak I don't think we should use it at
all. :)
