1. Do not dereference uninhabited types refs in Clone implementations …

   A reference to an uninhabited type should never be dereferenced:
   this is UB. `Copy` should not be implemented on such a type, and
   an upcoming Clippy lint (`uninhabited_reference`) may flag such
   dereferences as suspicious.
   
   Since those types are not structs, they do not need to get `Copy`
   and `Clone` implementations. A `missing!` macro limits code
   duplication.
