/// ### Explanation
///
/// This lint detects code that is very likely incorrect. When possible,
/// the compiler will attempt to detect situations where code can be
/// evaluated at compile-time to generate more efficient code. While
/// evaluating such code, if it detects that the code will unconditionally
/// panic, this usually indicates that it is doing something incorrectly.
/// If this lint is allowed, then the code will not be evaluated at
/// compile-time, and instead continue to generate code to evaluate at
/// runtime, which may panic during runtime.
/// This lint detects code that is very likely incorrect because it will
/// always panic, such as division by zero and out-of-bounds array
/// accesses. Consider adjusting your code if this is a bug, or using the
/// `panic!` or `unreachable!` macro instead in case the panic is intended.
