That would be historic reasons... I guess.
I don't really know if Squeak has or had code for setting the worldState 
ivar. In any case, that is indeed needed to be able to create new worlds.

Sounds very good. It is quite like I did the first version of SimpleMorphic.

Maybe it is easier if you first load the current version of 
SimpleMorphic, and then compare with the code you bring from Cuis 3.1, 
to see the differences... I did need to tweak a lot of details to make 
it load in Pharo, and I guess David did further changes to load into 
Squeak. If you just compare differences it will be easier to tell which 
are changes done for Pharo/Squeak compatibility and which ones are stuff 
that was later updated in Cuis...

Good luck!
