 This feature allows `&&`-chaining `let` statements inside `if` and `while` conditions, even intermingling with boolean expressions, so there is less distinction between `if`/`if let` and `while`/`while let`. The patterns inside the `let` sub-expressions can be irrefutable or refutable, and bindings are usable in later parts of the chain as well as the body.

 Let chains are only available in the Rust 2024 edition, as this feature depends on the [`if let` temporary scope](https://doc.rust-lang.org/edition-guide/rust-2024/temporary-if-let-scope.html) change for more consistent drop order.
