Comment:

 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++.
