/// use icu::locale::locale;
/// use tinystr::tinystr;
/// # use std::rc::Rc;

/// let locale = locale!("en-u-ca-japanese"); // English with the Japanese calendar
///
/// let calendar = AnyCalendar::new(AnyCalendarKind::new(locale.into()));
/// let calendar = Rc::new(calendar); // Avoid cloning it each time
/// // If everything is a local reference, you may use icu::calendar::Ref instead.
///
/// // construct from era code, year, month code, day, and a calendar
/// // This is March 28, 15 Heisei
/// let manual_date = Date::try_new_from_codes(Some("heisei"), 15, MonthCode(tinystr!(4, "M03")), 28, calendar.clone())
