Hello
The class comment of class 'Project' (Squeak 3.8 [1]) mentions
isolated projects.
In 5.1 this is no longer the case but a method
#isolatedProject
still exists (in class ChangeSet).
<citation>
In an isolated project, all new global variables (including new
classes) are stored in the project-local environment, and all changes
to preexisting classes are revoked when you leave the project.
</citation>
Is this mechanism superseeded by the still imcomplete Environments approach [2]?
In Squeak 5.1
Environment allInstances
gives
{Smalltalk}
[3]
How can I use an additional Environment in a subclass of
MorphicProject to get a similar effect.
Colin Putney writes after he had fixed project saving and loading [4]
<citation>
It should also work for multi-environment images, if we create UI for
setting the "current" environment, or actually make use of the
"environment" instance variable in Project.
</citation>

Hannes
