Virtual function - language feature

Example from C++:

class Animal {
 public:
  // Intentionally not virtual:
  void Move(void) {
    std::cout << "This animal moves in some way" << std::endl;
  }
  virtual void Eat(void) = 0;
};

// The class "Animal" may possess a definition for Eat if desired.
class Llama : public Animal {
 public:
  // The non virtual function Move is inherited but not overridden.
  void Eat(void) override {
    std::cout << "Llamas eat grass!" << std::endl;
  }
};

Example from Speedie:

class abc
 virtual DoSomething (|string| name)
 behaviour DoSomething
  printline "hello: $name"
