Although this permits additional diagnostics and optimizations which might be of some value, it is not consistent with long-standing usage, especially for a range of concurrent and sequential algorithms that rely on loads, stores, equality comparisons, and even dereferencing

This function performs an atomic comparison of the atomic object's value with an expected value, following the same value representation comparison semantics as `compare_exchange_strong`. It updates the expected argument on failure, operating entirely as
