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.

Best,

OK, thanks. By its name, I thought aligned_storage sounded like the right thing (and thus I included it in the subject line) but I wasn't sure how it fit in. I think aligned_storage<sizeof(T), alignment_of<T>::value>::type deserves its own template - maybe 'storage_for' ? Anyhow, I think I have everything I need, so away I go.... Tony
