You still have the buffer (the class has to go somewhere!), but 
it is implicit (you can't refer to it directly only through the 
class reference) and so is the destructor call, as opposed to the 
emplace + explicit buffer combo. In the latter case the class 
destructor will not be called automatically so you must do it 
yourself with `destroy`.
