new 關鍵字表示一個類（第2.3節）或者一個抽象類型（第2.8節）被實例化。后面跟著將要被實例化的類型的類型路徑（第3.7節）。它也可以列出顯式的類型參數（第3.2節），在<>中，通過逗號分隔。 在一個括號() 中跟隨構造器參數，同樣使用逗號分隔。 > The new keyword signals that a class (2.3) or an abstract (2.8) is being instantiated. It is followed by the type path (3.7) of the type which is to be instantiated. It may also list explicit type parameters (3.2) 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) { } } ~~~ main方法中我們實例化一個Main類自己的實例，有一個顯式的類型參數 Int 和參數 12跟 "foo" 。就如我們看到的，語法非常類似函數的調用語法（第5.9節），通常稱為構造函數調用。 > 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 (5.9) and it is common to speak of “constructor calls”.
