5.12 new

The new keyword signals that a class or an abstract is being instantiated. It is followed by the type path of the type which is to be instantiated. It may also list explicit type parameters enclosed in <> and separated by comma ,. After an opening parenthesis ( follow the constructor arguments, again separated by comma ,, with a closing parenthesis ) at the end.

class Main<T> {
  static public function main() {
    new Main<Int>(12, "foo");
  }

  function new(t:T, s:String) { }
}

Within the main method we instantiate an instance of Main itself, with an explicit type parameter Int and the arguments 12 and "foo". As we can see, the syntax is very similar to the function call syntax and it is common to speak of "constructor calls".
