This feels like it's testing `ranges::iterator_t` and `ranges::sentinel_t` more than anything in `enumerate_view`. I think we can remove it, or at least condense it to checking that we have a common range in both cases. https://github.com/llvm/llvm-project/pull/73617 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
