Should "Weakness weakness" hold up 3.5? (Was: RE: [Squeakfoundation]Re: [UPDATES] 3.5gamma)

For folks that haven't been following this too closely:

The bug that Andreas's fix addressed was: "adding inst var to ClassDescription breaks ClassBuilder" ( ).  According to Andreas, this bug only happened when one re-compiled Behavior, ClassDescription, or Class.  This bug was an obstacle for Nathanael Scharli's Traits project.  That bug appears to be fixed.

Tim discovered a separate bug, caused by how ClassBuilder validates the matchup between superclass format and subclass format during recompilation of a "variable" class with at least one "weak" subclass.  I posted a tentative fix.  I am not at all sure how many ways one could break that class-format validation logic.  The format validation check may well need more logic for matching the various class formats ( the original logic was "if newType ~~ oldType then throw error" ).

That's an interesting point. Does that mean we actually delay 3.5, when
the 3.6 update stream has already started? another question is, how did
we get into gamma, when apparently, one of our two goals for the release
isn't actually achieved?
