Order of implicitly declared special member functions

[hubert-reinterpretcast]

It is not clear what order implicitly declared special member functions are expected to be presented in an ObjectSequence that includes Objects that reflect upon such functions.

AN: That's an issue. Isn't the point of declaration of implicitly declared
special member functions already observable without the reflection TS? Is the
standard not saying anything about their point of declaration?

Left open as an issue to handle post-publication.
