//! Tamil (`ta`): the bare-tag alias of [`ta_in`](crate::ta_in).
//!
//! `ta` resolves to `ta-IN`, currently the only Tamil variant this crate
//! implements. It exists purely so the bare tag works without a region
//! subtag; it is not a claim that `ta-IN` speaks for every Tamil-speaking
//! region. Cardinal and ordinal are `ta_in`'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::{ta, Currency};
//!
//! assert_eq!(ta::to_cardinal(1234)?, "ஒரு ஆயிரம் இருநூற்று முப்பத்திநான்கு");
//! assert_eq!(ta::to_currency(42.5, Currency::INR)?, "நாற்பத்திரண்டு ரூபாய் ஐம்பது பைசா");
//! # Ok::<(), n2words::Error>(())
//! ```
