1 error[E0277]: the size for values of type `dyn Iterator<Item = &'a mut u8>` cannot be known at compilation time
2 --> $DIR/issue-20605.rs:2:17
4 LL | for item in *things { *item = 0 }
5 | ^^^^^^^ expected an implementor of trait `IntoIterator`
7 = note: the trait bound `dyn Iterator<Item = &'a mut u8>: IntoIterator` is not satisfied
8 = note: required because of the requirements on the impl of `IntoIterator` for `dyn Iterator<Item = &'a mut u8>`
9 help: consider mutably borrowing here
11 LL | for item in &mut *things { *item = 0 }
