/// ### What it does

/// Warns for a Bitwise XOR (`^`) operator being probably confused as a powering. It will not trigger if any of the numbers are not in decimal.

///

/// ### Why restrict this?

/// It's most probably a typo and may lead to unexpected behaviours.

///

/// ### Example

/// ```no_run

/// let x = 3_i32 ^ 4_i32;

/// ```

/// Use instead:

/// ```no_run

/// let x = 3_i32.pow(4);

/// ```
