Ah, thanks! However, the given example[1] does not violate the spec, since the spec says nothing about the order of inherited properties. Users may rely on a certain order, so the spec should at least state expicitly that the order of inherited properties is undefined. It might be preferable, though, to actually specify the order of inherited properties (first child, then parent, then grandparent, etc.) Also the spec should either define the order of runtime-created properties, or declare the order to be undefined. And the spec should not forget about properties of “use”d traits… [1] <https://3v4l.org/NLZNm> -- Christoph M.
