Hi Thorsten,
Adding the new requirement is out of the question, but it's definitely
possible to choose default construction or zero-initialization as
appropiate. And IMO that magic would be best placed within boost::in_place()
itself since it makes a lot of sense, given its nature, to do
zero-initialization for non-default constructible types.
With such a smart in_place factory, the optional swap implementation would
look exactly as you proposed it AFAICT.
Good job!
Best
