I'm pretty sure it's impossible to make Serial.helloWorld() a meaningful statement while using the HardwareSerial class (alternative is to rewrite entire class), because Serial is defined as HardwareSerial. However, you can make mySerial.helloWorld() a meaningful statement:

#include <Arduino.h>
class ScottSerial : public HardwareSerial {
public:
  ScottSerial() : HardwareSerial(Serial){
  }
  size_t helloWorld() {
    return println(F("Hello, world!"));
  }
};

ScottSerial mySerial;

void setup() {
  mySerial.begin(115200);
  mySerial.print("Okay it's hello world time.");
  mySerial.helloWorld();
}
void loop() {}
