no, and that’s why I didn’t considered it for now. this is an api change, non backwards compatible and then it breaks my own criteria about Pharo6 development: no more API changes. but yes, in general, I like the idea… just we cannot break things just like that (I know, I break things… but this is not willingly :P) Esteban
