I'm not sure "scrutinee" is correct here. The obvious "iterator expression" isn't really correct either, since it only has to implement IntoIterator. I guess this is fine for now.

See https://doc.rust-lang.org/nightly/reference/glossary.html#scrutinee.
I believe there are uses of "discriminant" elsewhere that should be changed to "scrutinee" but that is not for this PR.
