For Collage, I've pondered the question of Namespaces deeply and came to the
following conclusion:
Classes should have a 'namespace interface' like in VW5i. It just makes a lot
of sense.
Namespaces should subsume Smalltalk, Undeclared and all the shared pools.
Namespaces should be hierarchical, with Smalltalk as the root.
Namespaces should be able to import other Namespaces completely (just as
Classes import shared pools now).
Namespaces should be prominently visible in the Browser, being categorized just
like Classes.

Questions are:
Should Namespaces implicitly include all variables of their enclosing
Namespaces?
What about variable initializers? I don't really like them; would rather like
to have declarations only.
What about selective variable imports? Perhaps with renaming?
