## AI interpretation — verify before relying

Provides a fast lazy proxy object that defers expensive computation until the proxy is first accessed, calling a supplied function on first use rather than at instantiation.

Verdict: A stable, well-maintained utility for deferring expensive object initialization. Zero dependencies, permissive licensing, no known vulnerabilities, and broad Python version support make it a low-risk addition to any project needing lazy evaluation semantics.
