This subsection introduces the three ways of converting collections into iterators. For convenience, we combine them into a single example here. Note that in Husht you can select the mode of conversion by decorating the looping preposition `in`. This subsection introduces the three ways of converting collections into iterators. For convenience, we combine them into a single example here. Note that we have changed the loop specifications in the examples on the Rust side, because it seems more Rust-idiomatic to (for example) iterate on a reference to a collection than to call .iter explicitly.
