��This is what Smalltalk gives you for free.Sorrry for being rude but I wll use the two usually heavily annoying word, at least for me :DIt dependsSee there is a problem for Python here. Ideology.��The zen of python has been both a joke a serious mantra in the python world . Its a joke because its obviously oversimplify decision making in such a complex subject as language designe but is serious because it clearly illustrates the philosophy of its creator, Guido van Rossum.����Guido is not any less of a rock star to Pythoners than Alan Kay is for Smalltalkers. The zen has become so popular that is even included in python implementation and can be fetched as the link says using the "import this" in any implementation of Python. It's the very sould of python as messages and objects are the very soul of Smalltalk.So the problem here is that a live coding enviroment brakes the second rule. "explicit is better than implicit". Because live coding in Pharo and Smaltalk is about replacing old instances with new while keeping the state it non the less an implicit behavior and especially become is a no go scenario for python because not only replaces references to an object it also breaks the references to the other object. Of course the old object is garbage collected and RIP. Python follows this rule very strictly.Thus means that not only that Python will not offer a live coding enviroment in the future as the basis of its implementation . It means it does not want to. It may offer it as part of its extensive library.That also leads us to the inescapable conclusion that nothing comes free, everything has a cost. Because there will be scenarios you dont want to lose your old instances or not affect them at all and instead affect only the classes or maybe you dont even want to do that and want to do something else.
