If you look at First Steps I you might notice, that we use import to get holde of the flash.util.trace function. In Actionscript 2 we only could import classes. Is trace a class now?

The short answer is no. The long answer is, the new package concept of Actionscript 3 allows for defining functions as members of a package. These package members can be imported just like classes. Even package variables are possible. Here is a little example
//在AS3中允许你将函数当一个成员作包中（不必写在CLASS里面）

package {
        import flash.util.trace;
        import flash.display.MovieClip;

        public var surname:String = "Mueller";
        
        public function willi(){
                trace("willi " + surname + " was here");
        }
        
        public class Test1 extends MovieClip {
                public function Test1() {
                        willi();
                }
        }
}
