It seems to me that implementing the canonical assignment operator would work fine...

optional & operator=(optional const & rhs) { optional tmp(rhs); optional_swap(*this, tmp); return *this; }

I wish people would stop calling it that. It's easy, but it's overkill.

I know it is has a little more overhead
