[Laszlo-dev] LzNode.determinePlacement

[Adam Wolff]

I think that the right syntax here would be:
    super.appply( super.foo , arguments );

Of course all of this would have to be special-cased because there is no
real "super" object as such. That, in turn, might lead to confusion, since
one might expect a reference to super.bar to refer to my superclass's
value for bar, whatever mine may be.
