Well don't reduce/fold on a infinite stream :-)

I don't really buy into your argument that because there might be streams of size > Integer.MAX_VALUE that it implies sum() solves nothing, seems a rather extreme position to take. Do you think sum() solves nothing regardless of whether it returns an int or long?
