Could we get rid of these (and of the `none` token kind)? Ideally, I'd like to treat the token as a value type (so you can assign and copy it, but not mess with it), and one that is always valid (no uninitialized (none) state). https://github.com/llvm/llvm-project/pull/123521 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
