> Obtains the actual address of the object or function arg, even in presence of overloaded operator&

Operator overloading is a hell of a drug.
Also, I can all but guarantee that *someone* is going to specialize std::addressof for their cursed custom type to *also* change the output of that.
Whether this will be followed by std::actualaddressof or violence (or both), I do not know.

Hat tip to @mcc for nudging me into the depths of the C++ standard
