If you are talking about the
boost::recursive_wrapper<T>, which is part of the Boost.Variant library, then it is already default constructible.If you are talking about
boost::reference_wrapper<T>then this is not possible.boost::reference_wrapper<T>must behave exactly like a reference and you can not default construct a reference in C++.
