Gottlob Frege ha escrito:

This is *almost* correct. There's a typo in 1.33 Boost.TypeTraits docs
(corrected
in 1.33.1) by which the explanations on type_with_alignment and
aligned_storage
are swapped. So, what you want is

template <typename T>
struct uninitted
{
   aligned_storage<sizeof(T), alignment_of<T>::value>::type myT;

  void init_later(some_params)
  {
      new (&myT) T(some_params);
  }
};

Apart from this, your construct is OK and works as you expect. Actually,
this is
what aligned_storage is meant to be used for.
