As for your actual question: I'm not sure if I understand correctly, but I think you got things a little mixed up, or I'm not reading this the right way (also likely). Let's not use self anymore as an example, since that ended in fire and brimstone. Let's use something like this: A = source_var + 1 where `source_var` is a magic thing that refers to the target variable. Does that get the same idea across? Yes? Okay. The main reason that this would be difficult to translate isn't difficulty, but just readability. It's weird that using source_var would use __iadd__, but anything else would use __add__. Now, what I think everyone was telling you about as for "difficulty translating" is this: A = A + 1 ==> A += 1 Similar problem: semantics change. If someone decided to be weird and have __add__ and __iadd__ do two different things, this would completely break that. Granted, that's a stupid idea to begin with, but it's still poor justification for the code breakage. > When I was writing that I just thought, should I make a special note > that I am making it only for example, but then thought, oh that would > be too pedantic. > You say you have no time and write a whole page about it, > so don't blame me that I take too much time from you. > > Mikhail > _______________________________________________ > Python-ideas mailing list > Python-ideas@python.org > https://mail.python.org/mailman/listinfo/python-ideas > Code of Conduct: http://python.org/psf/codeofconduct/ > -- Ryan (ライアン) Yoko Shimomura > ryo (supercell/EGOIST) > Hiroyuki Sawano >> everyone else http://kirbyfan64.github.io/
