+ /// This lint suggests changing the following functions, when eager evaluation results in
+ /// simpler code:
+ /// - `unwrap_or_else` to `unwrap_or`
+ /// - `and_then` to `and`
+ /// - `or_else` to `or`
+ /// - `get_or_insert_with` to `get_or_insert`

/// **Why is this bad?** Using eager evaluation is shorter and simpler in some cases.

- /// **Known problems:** None.
+ /// **Known problems:** It is possible, but not recommended for `Deref` and `Index` to have
+ /// side effects. Eagerly evaluating them can change the semantics of the program.
