So that is the definition of "reusing storage" in the standard.
How about T* obj = new( (char*)data_+3 ) T ? Is it still ending
the object's lifetime? There is not such definition in the standard.
The standard is lacking a consistent definition of "storage"
and storage usage concepts.
I am free to argue:
variant<char, int> x;
//# starting reusing storage
x = 1; //standard is undefined
//# stoped reusing storage
If the "reusing storage" concept is undefined, the object liftime is undefined.
