You know your own codebase, and maybe this was safe for you to do. But in general, blindly applying such a blanket change has the potential to cause bugs, as these two are not always equivalent: for i := range k for i := 0; i < k; i++ In particular, if k is changed inside the loop they may be very different. https://go.dev/play/p/kAHcmu7377I (Yes, many people, myself included, would consider changing k inside such a loop to be bad coding style. But "bad style" doesn't mean it's not going to be done.) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
