Sorry, I didn't mean to throw the book at you. I only quoted the passage to 
point out that collect: is WAD.

That doesn't stop us from adding a new method to create a new dictionary by 
mapping values from an existing dict without affecting its keys. E.g.
        numberDictionary associationsCollect: [ :v | v asWords ].

Here is my first cut at it:

associationsCollect: aBlock
	| d |
	d = WriteStream on: (Array new: self size).
	self associationsDo: [ :assoc | d nextPut: assoc key -> (aBlock value: assoc 
value) ].
	^Dictionary newFrom: d contents
