in the traits slots plain object, in the 'isArgument: isA IfFail: fb' method,
the following code needs to be changed:
( inPlaceIfy: [copyIsArgumentForVisibility: v IfFail: [| :e | fb value: e] ] IfFail: fb )
to: ( inPlaceIfy: [ copyHolderForIsArgument: isA IfFail: [| :e | fb value: e] ] IfFail: fb )
Note, isArgument: isn't used in the 4.0 system as distributed, but hey, might as well fix it, right...
Also, I have conversed with Ole about his type inference code, and with someone else about a simplified outliner, both of which need a post 4.0 sanpshot to work. I was wondering if there is any plan to make a post 4.0 release, or if there was any way in which I could contribute to such an effort. (I do understand that the Self project has pretty much been shut down, but at least its worth asking...)
