[Pharo-dev] Issues 12717 and 12684

Guys, What is the relationship between issues 12717 and 12684 ? https://pharo.fogbugz.com/f/cases/12717/ReactiveVariable-NewValueHolder https://pharo.fogbugz.com/f/cases/12684/NewValueHolder-Enhancements Are the compatible ? Does one have to come before the other ? Are they both needed ? Since they change so much it is hard (for me at least) to judge whether it is safe to integrate them. Sven
