scanl in python

>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.


Don't know about the intend, but if it is duplicate of scanl(say on
Haskell), it is :

list(ireduce(add, [1], 42)) --> [42, 43]
list(ireduce(add, [1, 2], 42)) --> [42, 43, 45]
