This paper includes the following under the wording for [containers.sequences.inplace.vector.overview]:

LWG Review TODO: We need to review this last clause about constexpr. [...]

Has that happened?

[jwakely]

Yes, LWG reviewed all the wording

[frederick-vs-ja]

The operator<=> seems to suffer from the same problem as that in LWG4071. Is this already discussed or fixed?

[jwakely]

No, I don't think that was discussed.

[jwakely]

The reference implementation was incomplete 😠

    constexpr friend int /*synth-three-way-result<T>*/
    operator<=>(const inplace_vector& __x, const inplace_vector& __y)
