About
=====

This is a special implementation of promises in that it can be used both
for promise of a value and lazy evaluation. The biggest upside for this
is that everything in a promise can also be a promise, e.g. filters,
callbacks and errbacks can all be promises.

## AI interpretation — verify before relying

Vine implements Python promises for deferred computation and lazy evaluation, allowing callbacks, filters, and error handlers to themselves be promises for composable async workflows.

Verdict: Vine is a stable, well-maintained promise library with no dependencies, permissive licensing, and no known vulnerabilities. Its active repository (last commit 2026-08-12) and Production/Stable classifier signal production-ready stewardship. Suitable for async workflows where composable deferred computation is needed.
