I don't know if there is a way to avoid .cloned(), but without it, it doesn't seem to compile.

For the record, a way to avoid .cloned() is to use std::array::IntoIter::new(), which is available in the beta version of Rust, see https://blog.rust-lang.org/2021/02/26/const-generics-mvp-beta.html#by-value-array-iterator.
