locale - do not use a variable for it

Or use fallback, otherwise there will be problem with translations delivered from https://translate.wordpress.org

Example:

/**
 * Load translations.
 * Similar to the core function:
 *
 * @see load_plugin_textdomain
 */
protected static function load_translations() {

    $domain = 'some-domain';
    $locale = get_locale();
    $mofile = $domain . '-' . $locale . '.mo';

    // Try to load from the languages directory first.
    if ( ! load_textdomain( $domain, WP_LANG_DIR . '/' . $mofile ) ) {
        // Then try to load from our languages folder.
        load_textdomain( $domain, __DIR__ . '/../languages/' . $mofile );
    }
}
