-    inheritance: how about super()?
-    inheritance: new() method from parent used in child?
-    import/export of a class
-    type() should return different type for each class?
-    give error for shadowing (variable and argument) when defining a class or
-    interface, not later when compiling it.
-    object empty(), len() - can class define a method to be used for them?
-    how about lock/unlock?
-    When checking "implements" also check types of members and function args.

 - Use Vim9 for more runtime files.
