Apply the specified `visitor` to this modifiable variant by passing the value (of template parameter `TYPE`) this variant currently holds to the `visitor` object's `operator()`, and return the value returned by the `visitor`. The behavior is undefined if this variant is unset. Note that this method is selected only if the template parameter type `VISITOR` defines a `typedef` of `ResultType` in its public interface. Also note that this method is defined inline to work around a Windows compiler bug with SFINAE functions.
