Comment (by steven_watanabe):

 This shouldn't be part of optional.  It's functionality is orthogonal to
 that of optional.

 {{{
 #!c++
 // Allows storing T, but does not require T to be
 // a complete type except in construct/copy/destroy operations.
 // Requires: size >= sizeof(T)
 //           size % alignment == 0
 //           alignment % alignment_of<T>::value == 0
 template<class T, std::size_t size, std::size_t alignment>
 class typed_buffer {
 public:
     template<class T...>
     typed_buffer(T&& t...);
     ~typed_buffer();
     typed_buffer& operator=(const typed_buffer&);
     T& get();
     const T& get() const;
 private:
     boost::aligned_storage<size, alignment> _storage;
 };
 }}}
