I have 2 questions:

1. Do the interface functions have to be explicitly specified as
abstract?
   interface Foo {
    function bar();
   }
Because this runs fine for me with no errors.
They don't have to (currently) I weote the tests with abstract as i thought
this could be changed.....

1. What is the difference between the following:

   interface Foo {
   }
   class Boo extends Foo {
   }
and

   class Zoo implements Foo {
   }


a class can only extend ONE class/interface but it can implement multiple
interfaces. If you ask me i would not allow extending interfaces at all.
