Don't use misleading `<&[T; N] as IntoIterator>::into_iter`

See https://github.com/rust-lang/rust/pull/65819. Warned against by
default since Rust 1.41.

Right now `into_iter` returns references to objects inside an array
rather than moving the values (as one would expect) so it makes sense to
use `iter()` or for-in-borrowed (which calls the same thing) to retain
the behaviour but make it less confusing.
