//! Romanian (`ro`): the bare-tag alias of [`ro_ro`](crate::ro_ro).
//!
//! `ro` resolves to `ro-RO`, currently the only Romanian variant this crate
//! implements. The alias exists so the bare tag works without a region
//! subtag; it is not a claim that `ro-RO` speaks for every Romanian-speaking
//! region. Cardinal and ordinal are `ro_ro`'s own functions. Currency is the
//! one form a bare tag can't forward untouched: a language has no country to
//! take a default currency from, so [`to_currency`] takes the currency
//! explicitly.
//!
//! ```
//! use n2words::{ro, Currency};
//!
//! assert_eq!(ro::to_cardinal(21)?, "douăzeci și unu");
//! assert_eq!(ro::to_ordinal(2)?, "al doilea");
//! assert_eq!(ro::to_currency(1, Currency::RON)?, "un leu");
//! # Ok::<(), n2words::Error>(())
//! ```
