nyfmt PoC Examples (Documentation Only)

This directory hosts small snippets demonstrating reversible formatting goals. No runtime behavior changes or formatter are included in‑tree yet.

Examples to explore:

pipeline-compact.hako: pipeline style vs canonical call nesting
safe-access-default.hako: ?. and ?? sugar vs explicit conditionals
coalesce-range-roundtrip.hako: ?? and a..b triad (Before/Canonical/Round‑Trip)
compound-assign-roundtrip.hako: += triad (Before/Canonical/Round‑Trip)

NYFMT_POC=1 ./tools/nyfmt_smoke.sh

Notes: The real formatter prototype lives out of tree during early PoC. This folder documents intent and testable round‑trip expectations.
