The example in the paper was wrong, which was why it didn't work for Michael.

This program, or rather the variant of it that compiles and does what I intended, is now in homer.grace in the sample code directory.   I'm assuming that 

	def myParent is parent = t

means what I was writing as 

	uses t

where the super object is called myParent rather than super.
