    ///
    /// * it non-atomically modifies the locale object which is better regarded as constant;
    /// * it accesses the program environment without any synchronization.
    ///
    /// Canonical way to ensure safety is to call `setlocale()` as early as possible, prior to
    /// starting any more threads or enabling any POSIX signals.
