Description
There are special cases for std::reference_wrapper and recursive_wrapper in two places. One is in the get() call, the other in unwrapper helper class used by the visitor apply functions. This looks to me like there should be a way to unify this code, so that there is only once place that has the special code used by get() and apply_visitor().

Research direction
Start by locating the special handling for std::reference_wrapper and recursive_wrapper in get() and in the unwrapper helper used by the visitor apply functions. Compare the two paths and identify a shared place for that handling; done means both get() and apply_visitor() use the unified behavior without changing their existing results.
