Summary: - Looked into `or` macro impl to confirm if it supports short circuit evaluation (it does). Found that the documentation is wrong. It was [brought up in diff review](https://www.internalfb.com/diff/D2659697?dst_version_fbid=512163485661447&transaction_fbid=1230557897025059) 10+ years ago but wasn't corrected at the time Differential Revision: D99478498 fbshipit-source-id: 76d58748ecfc20f25e5cb7c20424a7a55cfe7b35
