Yes. It has a const void* overload. From a language-conceptual perspective, there's nothing odd about creating a const buffer from bit soup and then starting the lifetime of an object of another type in that buffer. >From a language perspective it's not a store. It just tells the language that an object of type T resides in that storage.
