That won't work, at least when using <compare>, which is what we with the
optimization want to deal with primarily.
Because std::partial_ordering etc. aren't implicitly nor explicitly
convertible to int or signed char etc.
Sure, one could in the testcase define its own std::strong_ordering etc.
and define a conversion operator for it...
