Hi guys, I think that we will rename all the asReactiveVariable that got introduced into their old name asValueHolder. And we will rename the class too to its old name. Why? I think that we should not change at the last moment ValueHolder into ReactiveVariable even if the name could be better: - First there are books around (and not only mine) that use this vocabulary for decades. - Second all the Spec tools developed by people right now do not work in latest 3.0. - I think that this change does not worth the noise it introduced: all the future changes of Spec-based tools that will be using asReactive will not work in Pharo3.0. We are in beta and now we should not change that. Then I would appreciate that we discuss it before. Because I would not change that even between versions of Pharo. Stef
