<!-- NOTE: For library features, please use the "Library Tracking Issue" template instead. Thank you for creating a tracking issue! Tracking issues are for tracking a feature from implementation to stabilisation. Make sure to include the relevant RFC for the feature if it has one. Otherwise provide a short summary of the feature and link any relevant PRs or issues, and remove any sections that are not relevant to the feature. Remember to add team labels to the tracking issue. For a language team feature, this would e.g., be . Such a feature should also be labeled with e.g., . This label is used to associate issues (e.g., bugs and design questions) to the feature. --The feature gate for the issue is . This tracking issue tracks the progress of the feature, which shall provide a saturating division for integer types. It is part of the ongoing effort to stabilize the type <!-- Include any open questions that need to be answered before the feature can be stabilised. --None.

I'm just curious: why was this feature stabilized so soon after being ? IIRC, usually features wait for at least a couple months before being stabilized.
AFAIK it has been a couple months, I think that it was just missing the tracking issue because they split this out as a partial stabilization from The original PR adding it landed in late august, , so it was a bit on the fast side but AFAIK we don't have any rule about how long things should remain on nightly before they're eligible for stabilization. Maybe we should? In this case I don't expect it will be a problem, this one seems pretty non-controversial, but I'm curious what the rest of thinks.
IIRC, is the only operator that panics. Although obvious, such behavior should probably deserve a improved documentation.
