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