The good news is that there are -> no vm changes -> no changes in the syntax So maybe it is done exactly as you suggest? I guess. For the integration, there are two steps 1) Layouts and new classBuilder This change is purely internal. There are Slot objects describing instance variables, but there are actually no new slot types and the definition template for subclassing is unchanged. You can look at an image like that here: https://ci.inria.fr/pharo-contribution/job/Slot/ 2) Actually add new Slots and support in the tools for those. Marcus
