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(). This method does not return a value. The behavior is undefined if this variant is unset. Note that this method is selected only if the template parameter type VISITOR does not define 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.
