Comprehensions with side effects feel scary indeed. But I could see myself using some variant of the "cumsum" example (for scientific work at the command prompt): >>> x=0; [x:=x+i for i in range(5)] Here the side effects are irrelevant, the "x" variable won't be reused. But it needs to be initialized at the start of the comprehension. I would happily get rid of the side-effects, but then what would be a non-cryptic alternative to the above example?
