- Detect one element array of `Range` type, which is potentially a typo:
`for _ in [0..10] {}` where iterating between `0` and `10` was intended.
(#23141)
- Suggest `.bytes()` and `.chars()` for `String`.
- Suggest borrowing or `.iter()` on arrays (#36391)
- Suggest using range literal when iterating on integers (#34353)
- Do not suggest `.iter()` by default (#50773, #46806)
