Richard Feldman (Aug 08 2026 at 01:45): Richard Feldman (Aug 08 2026 at 01:45):we currently have an assumption that iterators are reversible, but I think that was a mistake in hindsight. Some custom iterators simply aren't (e.g. an infinite range), or have terrible performance if you reverse them (e.g. a linked list), and I think it's better to just expose things like List.iter_rev from only the data structures that can reasonably offer reversed iterators, instead of having the reversal operation in Iter itself.
