Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 54s
js-on-sx: js-dict-get-walk falls back to Object.prototype
Object literals didn't carry a __proto__ link, so ({}).toString()
couldn't reach Object.prototype.toString. Added a cond clause: if
the object has no __proto__ AND is not Object.prototype itself,
walk into Object.prototype. Now ({}).toString() works, override
of Object.prototype.toString propagates, and ({a:1}).hasOwnProperty
('a') returns true. built-ins/String: 69/99 → 71/99 (canonical),
71/99 → 74/99 (isolated). conformance.sh: 148/148.
