1,2) Atomically assigns desired to the atomic variable. Equivalent to store(desired).
It is deprecated if std::atomic <T>::is_always_lock_free is false and overload (2) participates in overload resolution.
(since C++20)3,4) Atomic variables are not CopyAssignable.

[edit] Notes
Unlike most assignment operators, the assignment operators for atomic types do not return a reference to their left-hand arguments. They return a copy of the stored value instead.
