But now try to find people who would be adversely affected by your proposed change. Unless you do it in a purely backward compatible way such as the local shadowing of iter(), you WILL break other people's code. What you've shown is that a small handful of people have wondered at the reiterability of generators, which is NOT the same as wanting a warning in these situations. Even if we consider that every single upvote represents a person who wants this feature, you've shown, what, a thousand people total? Across the whole world? That's not exactly an overwhelming number of people, and hardly enough to make a backward-incompatible language change. Let's go back to your earlier incredulity: > And I have to say I'm surprised by the responses. Does nobody else hit bugs > like this and wish they were automatically detected? You've found a dozen questions that have been upvoted by a maximum of 124 people, by your own count (I didn't bother going through all the questions to check). Let's make some VERY generous estimates: 1) Every upvote represents a unique person (pretending that nobody browses multiple questions and upvotes them all) 2) Each of those people agrees with your proposal 3) The total upvote count is 1000 (feel free to go and sum them for me, I can't be bothered) 4) For everyone who upvotes, nine others don't bother to upvote That'll give an incredibly generous figure of 10,000 Stack Overflow users who might support your proposal. Stack Overflow has 21 million users [1]. If we assume that those who answer their survey are representative (impossible to prove, but the best we can do), about half of those are Python users [2]. That's roughly 10,000,000 Stack Overflow users who use Python. Even if we assume that Stack Overflow users are representative of the internet at large (they're definitely not, but again, it's good to at least having some figures), that's 0.1% of people. So..... yeah, I'm not surprised that none of us here has run into a problem. I strongly recommend reconsidering the "shadow iter() in your own code" solution, as it is entirely backward compatible.
