-This  subsection introduces the three ways of converting collections into iterators. For convenience, we combine them into a single example here. Note that Husht will provide three different prepositions for looping as syntactic sugar for the three methods of obtaining an iterator from the collection. The proposal below uses `in` as Rust does, `from` for borrowing, and `on` for borrowing mutably. We should also consider `in`, `&in`, and `&mut in`, as that might be more Rust-y.
