| Return the result of `t1 <=> t2` expression if this expression is valid. Otherwise, if `t1 < t2` and `t2 < t1` expressions are well‐formed and return boolean‐testable results, use the `<` operator to emulate `<=>`. Otherwise this function is not defined and does not participate in overload resolution. Note that this is an implementation of the exposition‐only callable object `synth‐three‐way` defined by the ISO C++20 Standard [expos.only.entity].

| A type returned by `SynthThreeWayUtil::compare<t_TYPE1, t_TYPE2>`. Note that this is an implementation of the exposition‐only type alias `synth‐three‐way‐result` defined by the ISO C++20 Standard [expos.only.entity].
