I understood that part but don't understand the intent of:

aBlock ensure: [ object := previous ]

ifTrue: [ ^ self ].
anObject isNil
ifFalse: [ seen add: anObject ].
That part just tries to avoid to go into recursion if a described
object refers to another object that descriptions refer back to the
original object. That was requested at some point in the past, but I
never dependent on that myself.
