/// The `edition_2024_expr_fragment_specifier` lint detects the use of
/// `expr` fragments in macros during migration to the 2024 edition.
///
/// The `expr` fragment specifier will accept more expressions in the 2024
/// edition. To maintain the behavior from the 2021 edition and earlier, use
/// the `expr_2021` fragment specifier.
///
/// ### Example
///
/// ```rust,edition2021,compile_fail
/// #![deny(edition_2024_expr_fragment_specifier)]
/// macro_rules! m {
/// ($e:expr) => {
/// $e
/// }
/// }
///
/// fn main() {
/// m!(1);
/// }
/// ```
///
/// {{produces}}
///
/// ### Explanation
///
/// Rust [editions] allow the language to evolve without breaking backwards
/// compatibility. This lint catches code that uses [macro matcher fragment
/// specifiers] that have changed meaning in the 2024 edition. If you switch
/// to the new edition without updating the code, your macros may behave
/// differently.
///
/// In the 2024 edition, the `expr` fragment specifier `expr` will also
/// match `const { ... }` blocks. This means if a macro had a pattern that
/// matched `$e:expr` and another that matches `const { $e: expr }`, for
/// example, that under the 2024 edition the first pattern would match while
/// in the 2021 and earlier editions the second pattern would match. To keep
/// the old behavior, use the `expr_2021` fragment specifier.
///
/// This lint detects macros whose behavior might change due to the changing
/// meaning of the `expr` fragment specifier. It is "allow" by default
/// because the code is perfectly valid in older editions. The [`cargo fix`]
/// tool with the `--edition` flag will switch this lint to "warn" and
/// automatically apply the suggested fix from the compiler. This provides a
/// completely automated way to update old code for a new edition.
///
/// Using `cargo fix --edition` with this lint will ensure that your code
/// retains the same behavior. This may not be the desired, as macro authors
/// often will want their macros to use the latest grammar for matching
/// expressions. Be sure to carefully review changes introduced by this lint
/// to ensure the macros implement the desired behavior.
///
