Sounds like you want
type_with_alignment<T>::type storage;
new ((void*)&storage) T(x, y, z)
Can you really do anything to make this cleaner? I guess:
aligned_storage<T> storage;
new (storage.bytes) T(x, y, z);
might be a help. What else are you gaining? And how do you destroy
the T? If not explicitly and you don't have a "constructed" flag,
you're going to have exception-safety problems.
