Comment:
Hi Vicent,
Replying to [comment:19 vdelecroix]:
> 8. Why not implementing `_richcmp_` (see #18305)? You would end up with
less code.
Indeed it would. It seems that `element_wrapper` is not using my
`_richcmp_` and fixing `element_wrapper` seems a bit more work (and not
suitable for this ticket here).
