>From the Zen of Python: "Special cases aren't special enough to break the rules." I think that the test for an empty iterator makes ireduce() unintuitive. Try asking someone who has not followed the discussion what list(ireduce(add, [], 42)) might produce, given that list(ireduce(add, [1], 42)) --> [43] list(ireduce(add, [1, 2], 42)) --> [43, 45] list(ireduce(add, [])) --> [] list(ireduce(add, [1])) --> [1] list(ireduce(add, [1, 2])) --> [1, 3] I suspect that [42] will be a minority vote.
