Thank you. Clang-14 probably has incomplete ranges implementation, and we are not testing against it. Pushed a commit (4fa696d) to address unsupported compilers but will leave the issue open to revisit when ranges support appears complete.

If it is still not compiling, it would be appreciated if you could report back.

Should have been fixed now. If this is still an issue, please comment and report back.
