  Python's equivalent of Rust's Enums would be the __match_args__ machinery rather than enums themselves, ironically. They aren't as ergonomic or type-safe, and rather surprisingly the match statement is not an expression in Python's grammar, but regardless of its problems the match statement is very powerful, even more so than static equivalents.

    IMO Python's equivalent of Rust's Enums would be `typing.Union` [1]. It is more ergonomic and type-safe, and mypy supports type narrowing [2] and exhaustiveness checking on it [3].
