Wonderful to have progress on this important topic - thank you! Sorry I haven't been following closely (maybe you addressed it already), but pushing up instance variables has a dangerous limitation - instances lose any data held in that var. I guess it's because it's deleted from the subclass prior to adding to the superclass to avoid duplicating. One solution would be to add a var to the superclass with a mangled name, copy the data for all instances, remove the var from the subclass, and then rename the mangled var. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
