## AI interpretation — verify before relying

Provides an LRU cache decorator for async functions that deduplicates concurrent calls and supports TTL expiration with jitter, mirroring Python's functools.lru_cache for asyncio.

Verdict: Production-ready async caching library with low install friction, active maintenance, and no known vulnerabilities. The single-event-loop constraint is documented and manageable for typical asyncio applications. Recommended for projects needing efficient memoization of async functions with optional TTL support.
