Citation needed, how do you calculate that they affect fewer people than your proposal? The byte/str comparison warning relates to Py2/Py3 changes, which affected huge numbers of people; locale-dependent encodings affect everyone whose systems default to those encodings; and I don't know what the debug build does exactly, but it's specifically meant to cover things that are too expensive to check for normally. Also, question: Would your proposal even be useful to people if they had to run Python with a special parameter to get it? Wouldn't it be just as easy to shadow iter(), like I have already suggested multiple times as a much better way to do this? > And then Chris' messages started rolling in. Backward compatibility is WAY more important than a lot of proposals seem to acknowledge. You're welcome to hate me for saying it, but frankly, you're also welcome to ignore my posts. I don't have to prove anything to you; the onus is on you to demonstrate the value of your proposal, and at the moment, you've shown a benefit in a very small number of cases, contrasted with a potentially huge number of situations where this would create a spurious warning. Blaming me for the pushback is a tad unfair. But that's your prerogative.
