function with the same signature as the original (same access modifier, same name, same arguments, and

the function declaration just before the function keyword.
The haXe compiler accepts an - override switch; when this switch is on, the compiler will throw an
error whenever an overridden function without the override keyword is encountered. Leaving this
switch always on is considered a good practice and helps to spot conflicting names.
