Re: Etoys Again: saving a project

The error has nothing to do with Etoys, but is in the way Projects are
saved and loaded.

I tried to follow along, by just reading the code, but with renamed and
reshaped classes, fake objects, outpointer arrays.... I must admit I am
just overwhelmed by 'details'. I get there is this class MultiNewParagraph,
that is expected to be in the structures instance variable of the
SmartRefStream class, and for one reason or another, it is not there (maybe
not surprising as it is not in the image, being renamed to  NewParagraph as
I can see in the method initKnownRenames of the SmartRefStream class).

Is there any document explaining the base vocabulary and principles of
Projects, because without, I can't make much sense of all this.
And having just read that "Smalltalk's design, with it's emphasis on
messaging and late binding, was intended to create a metamedium where users
could explore and modify the system itself", I'm feeling pretty dumb right
now...🤯. Apparently, people were much smarter in those days...
