Optional proposal file. In case links don't work.

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

// 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;
};
