Ok, wow. Didn't know that. So, whenever I change a class, I have both the old version and the new version co-existing? And then the instances are told to become: instances of the new class? Thanks for the info. 2012/12/1 Alexandre Bergel <alexandre.bergel@me.com>:
Are there some vital things that are impossible if #become: is missing? (no irony in my question, I just don't know)
Changing a class on the fly. #become: is used behind the scene
