Hi Viktor,Thanks for the response! I see what you mean, it’s a good point that single-element streams are just as valid as streams with other numbers of elements.The weird part for me, though, is getting the folded result out of the stream at the end (which, while not always, I believe will be the

Hi Tyler,
Thank you for the kind words -- they are much appreciated. And you have a very

Thanks for the JEP and your talk, Viktor! I think `Stream::gather` will be super useful in my day-to-day as a Java developer.I’m curious why `fold` is being implemented with gatherers. I recognize `Gatherer` is designed to support intermediate operations, but `fold` feels inherently like a termin
