* `break` and `continue` statments local to the would-be closure are allowed * don't lint in const contexts * don't lint when yield expressions are used * don't lint when the captures made by the would-be closure conflict with the other branch * don't lint when a field of a local is used when the type could be pontentially moved from * in some cases, don't lint when scrutinee expression conflicts with the captures of the would-be closure

Additionally, it would be helpful if you split the PR or commits for each issue next time. I'm okay with that this time. |

yield expressions (used in async await) can't be moved into a closure. There is a test now. |

The inference from #6137 still exists so I'm not sure if this should be moved from the nursery. Before doing that though I'd almost want to see this split into two lints. One suggesting
map_orand the other suggestingmap_or_else.map_or_elsetends to have longer expressions for both branches so it doesn't end up much shorter than a match expression in practice. It also seems most people find it harder to read.map_orat least has the terseness benefit of being on one line most of the time, especially when theNonebranch is just a literal or path expression.changelog:
