--- Comment #8 from S. Davis Herring <herring at lanl dot gov> --- I looked at P2266R3 again; it claims that the conversion function case (in #7) is actually covered by P1825R0. I think that case is questionable, since it still refers to "overload resolution to select the constructor for the copy" and there's no constructor involved when a conversion function is used. (In particular, it isn't the case that the A object is converted to a Dest temporary that is then used as the argument to Dest(Dest&&), since that would be a second user-defined conversion.) If we consider the intent in P1155R3, though, it's pretty clear that that's just a wording oversight, so it's not unreasonable that GCC and Clang (but not ICC) accept template Dest withMove<A>(); in C++20 mode. That means that we don't have to distinguish C++20 and C++23 for this discussion (at least outside of weirder cases like returning a reference).
