Yes, I think that's what I did:

UndefinedObject subclass: #Trampoline
	instanceVariableNames: 'collection iterationMessage '
	classVariableNames: ''
	poolDictionaries: ''
	category: 'Collections-Support'

This may have gotten mangled between fixing a typo and creating the  
changeset.  I hope the new changeset is better.
