> The following code appears to show that final is being applied inconsistently.  A final list can be amended but an object that manipulates a lsit that is final cannot.  In the former case the final is being applied to the reference and in the later, it is being applied to the object.
> {code}
>  class Blah {
>   def list = []
>    public plus ( item ) {
>      list += [ item ]
>      return this
>    }
> }
> class Foobar {
>    final static blah = new Blah ( )
> }
> final x = []
> x += [1]
> println ( x )
> Foobar.blah += 1
> println ( Foobar.blah.list ) 
> {code}
