``` error[E0599]: no method named `map` found for struct `Vec<bool>` in the current scope --> $DIR/vec-on-unimplemented.rs:3:23 | LL | vec![true, false].map(|v| !v).collect::<Vec<_>>(); | ^^^ `Vec<bool>` is not an iterator | help: call `.into_iter()` first | LL | vec![true, false].into_iter().map(|v| !v).collect::<Vec<_>>(); | ++++++++++++ ``` We used to provide some help through `rustc_on_unimplemented` on non-`impl Trait` and non-type-params, but this lets us get rid of some otherwise unnecessary conditions in the annotation on `Iterator`.
