And long can hold the result of MAXINT additions?

stream are sized is store in a long if a size if definite or can be infinite so it solves nothing. I don't quite understand the above sentence. Are you suggesting reducing/folding on a infinite stream? yes, and you throw an exception when you've done, Brian talk about that.

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?
