fix(compiler): avoid false-positive for destructured hook identifiers that are only called

Open karankumbhare90 opened this issue 2 months ago • 1 comments

Summary:

  • Reproduced a false-positive where destructuring a hook-named identifier from an object and then calling it is flagged: const { useValue } = hooks; useValue(); // should be allowed

  • Root cause: The compiler treated hook-like names as values too eagerly without confirming how the binding is used.

  • Fix: For each Place in the HIR, compute whether it is only used as the callee of calls. If so, skip the "Hooks may not be referenced as normal values" error for KnownHook kinds. Otherwise preserve existing behavior.

Repro (Playground): https://playground.react.dev/#N4Igzg9grgTgxgUxALhHCA7MAXABFMBANQEMAbKBXAXlwAoBKGgPn0IFkEBbCOxl3ABYATABpcAbQC6DANwAdDOix4AFhAgBrMDVzA2xcpVwBfBRkXKcuAGIkAlmR21+1VsEW5cVvPoKGKKmRcKhNddS0wcy8fXAA3Iypaf1JAxmjcGARsWAxcAB4wAAcSDGZgBMCTfIB6YtLmRRNFS0xrAHUIGG1dV3dPbzbfA1TKYLjTcI1tDNjK41o49IGsnJg8wpKyisTquq3GjGaMEFE0TAAzewBzFBB7LiKuvGwATyKqfQAFCmv7DAA8kVsPY2pMLjAIFxcAByABGJDhCDIAFoir9-iisiQ4NgUehHo4EDAagATew4GHmRR0DxHXBgEggsBXBA6H5QP6A4GgrByU7gdQAdwAkhhsMSMOQwCgLtKECYgA

Notes:

  • This change is conservative: it only suppresses the error when every usage of the Place is a direct call callee.
  • I couldn't run the full repo tests locally due to Windows scripting/tooling differences; CI will run tests in the PR. I added a local code change and explanation; happy to add fixture tests if maintainers prefer and can advise where they want them.

Closing as this does not meet baseline criteria for PRs: no tests, no alignment with the team that the fix is the correct approach, etc.
