Personally, I do not like exposing type traits that aren't for use with the STL. One idea would be to remove the type trait from TokenKinds.def and instead manually add `BTT_IsDeducible` to: https://github.com/llvm/llvm-project/blob/c61f0a8e94004b05d9ec115d3bff8cff331b4491/clang/include/clang/Basic/TypeTraits.h#L21 along with a comment explaining that this is for internal use only rather than be exposed to users. (You'd have to see if there are other places using `TYPE_TRAIT_2` that might need adjustment as well.) Then we can remove the release note, error checking can become assertions, etc. https://github.com/llvm/llvm-project/pull/89358 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
