After trying to clean SystemDictionary I think that at the end what
should be done
(I proposed that but we did not do it at the end because we were burnt):
- is to keep Smalltalk as a placeholder for image related behavior
like saving, abandonning sources,...
- have a namespace class which support class/global management
I proposed a migration path but (I did not have the energy to have a
prototype of what I was proposing
May be I should- but back then I was burnt and sick of complains).

But did you enter big reports in mantis because this is the only way
to keep track
of bug and that we can fix and improve them.

We were always aware that we were introducing changes and that it
would affect people
this is always this tension between moving and staying at the same

Not to do it. Smalltalk is cool :)

We got sick of squeak. :)

because it was incremental and not that discussed. Even if it makes a
lot of sense
to have SmalltalkImage and SystemDictionary separate classes.

What I can tell you is that we always try to pay attention and this is
also why we got burn. We had this vision (dan one) that a system should
be lean and clean that people can really learn from it. Now some
were made and may be they were not optimal....
