I believe the indices in your examples are updated in the wrong place. The following seems to do what I believe you expect: https://go.dev/play/p/U2YQM3fOz98

We also have a reflect-based implementation, but this incurs a significant performance cost and so cannot be used as the default implementation (users are able to select this through build tags). With the advent of function iterators it would (superficially) appear that there would be a path towards making this kind of iterator value more generally available. This currently does not work (for example here: https://go.dev/play/p/yb-c7f_E7t3 and https://go.dev/play/p/T3lbn-XrnYd, both of which are surprising from a the perspective of a pre-rangefunc Go user). This is not the case with map iterators since there is no corresponding index that is meaningful in that context, but this is a matter of runtime implementation. Is there any chance that something like this would be supported in the future? Dan -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
