This looks great! In other languages, I frequently miss having a simple, widely adopted abstraction like Rust's &[T]; C++ iterators are kind of a pain by comparison, and often feel like an abstraction maybe one level too low/broad (as always, concepts could help that). It's nice that they the documented the interaction with the GC too.
