First,



thank you for the 'gather' tip. It appears to work just fine.



Next pharo-ism is something named 'groupedBy:'



Collection >> groupedBy: aBlock

"Answer a dictionary whose keys are the result of evaluating aBlock for all my elements, and the value for each key is the selection of my elements that evaluated to that key. Uses species.



Example of use:

(#(1 2 3 4 5) groupedBy: [ :v | v odd ]) asString >>> 'an OrderedDictionary(true->#(1 3 5) false->#(2 4))'

"





This looks like 'select:' to me.


any objections/insight much appreciated.

thx
