/// ### Explanation
///
/// In Rust 2021, one of the important introductions is the [prelude changes], which add
/// `TryFrom` and `TryInto` into the standard library's prelude. Since this results in an
/// amiguity as to which method to call when an existing `try_from` or `try_into` method is
/// called via dot-call syntax.
/// `TryFrom`, `TryInto`, and `FromIterator` into the standard library's prelude. Since this
/// results in an amiguity as to which method/function to call when an existing `try_into`
/// method is called via dot-call syntax or a `try_from`/`from_iter` associated function
/// is called directly on a type.
