Exception Handlings. Actually, there is one: BOOST_NO_EXCEPTIONS but I
cannot compile with -fno-exceptions under gcc (some try / catch were still
there).

Actually postponed<> looked like the following and initilialized<> is a list
of booleans set to false:
template <typename T>
struct postponed : storage<T>, initialized<T>
{
typedef T type;
typedef storage<T> storage_t;
typedef initialized<T> initialized_t;
template <int I>
partial<typename type_at<storage_t, I>::type::value_t> & set()
{
static_cast<typename type_at<initialized_t, I>::type &>(*
this).value = true;
return static_cast<typename type_at<storage_t, I>::type &>(*
this).value;
}
template <int I>
typename type_at<storage_t, I>::type::value_t const & get()
const
{
return static_cast<typename type_at<storage_t, I>::type
const &>(* this).value.get();
}
};
