Trivial Destructibility and Necessity of Calling Destructor
https://stackoverflow.com/questions/11781221/trivial-destructibility-and-necessity-of-calling-destructor
QuestionAnswer8edited Aug 2, 2012 at 16:10According to the C++ Standard (section 3.8), you can end an object's lifetime by deallocating or reusing its storage. There's no need to call a destructor that does nothing. On the other hand, letting the compiler optimize away an empty destructor usually results in cleaner and simpler code. Only if you can save substantial additional work, such as iterating through the collection, would you want to special-case trivial destructors.
