[Cuis-dev] Namespaces?

[Luciano Notarfrancesco]

Oh, I haven't thought about doing that trick with Symbol, seems to make a
lot of sense. Maybe making Symbols unique within a package instead of
globally would be enough. Still there might be a lot of work to do in order
to make all tools work as expected, not sure. I'll keep this technique in
mind and maybe try some experiments, thanks!
