The antlrcpp::Any::is function should not throw a std::bad_cast exception if the contained type can't be cast to the requested type, but should instead just return a boolean result. Add a boolean parameter to the private getDerived helper function to allow callers to specify whether or not they want the cast results checked. In the is() function, pass false for this parameter; in the as() functions, pass true.
