Comment #1 on issue 3871 by thomas.h...@gmail.com: [Failing Test] 1.3 ReduceTest.testReduceCollection3Arguments http://code.google.com/p/pharo/issues/detail?id=3871 Name: Collections-Abstract-ThomasHolzer.130 Author: ThomasHolzer Time: 15 April 2011, 2:55:10 pm UUID: 2d36eaff-6047-0142-b9e1-802b35007254 Ancestors: Collections-Abstract-StephaneDucasse.129 Fix for issue 3871. Problem was caused by an incorrect implementation of reduce: on Collection. This implementation only worked for blocks with 2 arguments. Issue was fixed by converting the collection to a sequenceable collection and reusing the reduce functionalitz of that one.
