/// The `illegal_floating_point_literal_pattern` lint detects
/// floating-point literals used in patterns.
///
/// ### Example
///
/// ```rust
/// let x = 42.0;
///
/// match x {
/// 5.0 => {}
/// _ => {}
/// }
/// ```
///
/// {{produces}}
///
/// ### Explanation
///
/// Previous versions of the compiler accepted floating-point literals in
/// patterns, but it was later determined this was a mistake. The
/// semantics of comparing floating-point values may not be clear in a
/// pattern when contrasted with "structural equality". Typically you can
/// work around this by using a [match guard], such as:
///
/// ```rust
/// # let x = 42.0;
///
/// match x {
/// y if y == 5.0 => {}
/// _ => {}
/// }
/// ```
///
/// This is a [future-incompatible] lint to transition this to a hard
/// error in the future. See [issue #41620] for more details.
///
/// [issue #41620]: https://github.com/rust-lang/rust/issues/41620
/// [match guard]: https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards
