The idea is to return a "map" of the original series from original values to some derived value. For example, maybe we have a series of Strings, and I want to create a map from those Strings to their md5sum values.
I can code this as
Dictionary withAll: (setOfStrings collect: [:each | each -> (Security.MD5 new hash: 'Hello World')])
but I really would rather capture this as a common method. What would you call it?
