Hi, do you have some proposals for a better name for the message named #aggregateRuns? (#(1 2 3 4 1 2 3 5 6 ) aggregateRuns: [ :each | each = 4]) >>> #(#(1 2 3) #(4) #(1 2 3 5 6)). (#(1 2 3 4 1 2 3 4 5 6 ) aggregateRuns: [ :each | each = 4]) >>> #(#(1 2 3) #(4) #(1 2 3) #(4) #(5 6)). ((1 to: 12) aggregateRuns: [ :each | (each \\ 3) = 0]) >>> #(#(1 2) #(3) #(4 5) #(6) #(7 8) #(9) #(10 11) #(12)). The current comment is: "Answer a new collection of the same species as the receiver with elements being collections (of the receiver species) containing those elements of the receiver for which the given block consecutively evaluates to the same object." https://pharo.fogbugz.com/f/cases/20864/add-examples-to-SequenceableCollecti...
