> Throwing move is super weird too. I believe that it was a mistake to not treat user move like C++11 destructors and default to noexcept(true) on them. But it is what it is.
I think you're missing a fair deal of insight into the issue.
The move semantics proposal documents this aspect in clear and unambiguous terms:
- Almost any class should be able to create a nothrow move assignment operator.
- a basic requirement is that a class must have a valid resource less state (i.e., remain in a valid state after having been moved)
- those that can't, shouldn't define move semantics.
