How close it to Java ? The documentation shows a lot of similarity but I need to investigate for non-trivial projects. There is a lot of Java software that can be ported. But it all boils down on how close it is. The closer, the less porting effort.

We definitely need something like this.

public class Hello {

    public static void main(String[] args) {

        Chatter chatter = new Chatter();

        String text = "Hello " + chatter.getWord() + "!";
        System.out.println(text);
        free text; // destroy object and reclaim the memory

        free chatter; // destroy object and reclaim the memory

        // System.out.println(chatter); // use after free NEVER compiles
    }

}

// OR:

public class Hello {

    public static void main(String[] args) {

        Chatter chatter = new Chatter();
        defer free chatter;

        String text = "Hello " + chatter.getWord() + "!";
        defer free text;
        System.out.println(text);
    }
}
