Summary: Error loading class in Interpreter

Initial Comment:
I compiled the attached file and played around with anonymous inner classes
in the Interactios pane as shown below:

> UnaryFun f = new UnaryFun() { return
Invalid class body
> UnaryFun f = new UnaryFun() { return
Invalid class body
> UnaryFun f = new UnaryFun() { Object apply(Object arg) { return arg * arg;
}}
Static Error: Bad type in numeric expression
> UnaryFun f = new UnaryFun() { Object apply(Object arg) { return
(Integer)arg * (Integer)arg; }}
>

I got the following error message:
