why

Hand-kept RTL lists, week-start tables and weekend rules go stale and miss cases like fa-IR's one-day weekend. The runtime knows; anylocale exposes it as one cached record, resolves fallback chains on real data, and works across the property and method forms engines ship.

usage

anylocale("ar-EG").direction         // "rtl"
anylocale("en-GB").weekStart         // 1 — Monday; en-US is 7 (ISO numbering)
anylocale("fa-IR").weekend           // [5] — Friday only
anylocale("ar-EG").timeZones         // ["Africa/Cairo"]
anylocale(["xx-Nope", "de-DE"]).tag  // "de-DE" — first tag with data wins
anylocale.supported                  // Intl Locale Info present?

not for

Naming a locale (that is anyaround), translating anything, or detecting the user's locale.
