 - Boxed slices implement [`IntoIterator`] in *all* editions.
 - Calls to [`IntoIterator::into_iter`] are *hidden* in editions prior to 2024 when using method call syntax (i.e., `boxed_slice.into_iter()`). So, `boxed_slice.into_iter()` still resolves to `(&(*boxed_slice)).into_iter()` as it has before.
-- `boxed_slice.into_iter()` changes meaning to be the call [`IntoIterator::into_iter`] in Rust 2024.
