Thanks @usx95  for the detailed feedback! I've pushed an updated revision addressing both comments. I narrowed the implementation to keep the PR focused on the root cause by reverting the broader isImplicitObjectMemberFunction() change and retaining only the changes required for the fix. I also rewrote the regression tests to include use-after-scope scenarios so they verify the lifetime analysis and loan flow, rather than only ensuring the compiler no longer crashes. Please let me know if there's anything else you'd like me to adjust. Thanks again for the review!
