Great! How long has it been there? :) Apparently since 2012 - can't really remember
My gosh, I remember searching for that years ago.
And why is it in SequenceableCollection and not SortedCollection? Hmm, probably because any SequenceableCollection could be sorted up front, like in ((1 to: 100) collect: [ :i | 100 atRandom ]) sort.
Ok, makes sense.
BTW, we also have #threeWayCompareTo: (the spaceship operator, aka <=>)
(((1 to: 100) collect: [ :i | 100 atRandom ]) , #(66)) sort findBinaryIndex: [ :x | 66 threeWayCompareTo: x ]
I think that method is part of the SortFunctions package I ported. It is not in my Pharo 5 image at least. Regards! Esteban A. Maringolo
