Other than PluggableSet, something like Unix's sort and uniq combo would work: condenseOnFirst: aCollection | lastSelected | ^ aCollection sorted select: [:each | (lastSelected isNil or: [lastSelected first ~= each first]) ifTrue: [ lastSelected := each. true] ifFalse: [false]]

Say I have a collection like #('ab' 'ac' 'ba' bc') and I want to condense it so that a certain attribute is unique. In this example, say the first character, so I want one object where the first character is $a and one $b, but I don't care which object i.e. 'ab' or 'ac' for $a, but not both.
Is there an elegant way to do that?
