Also, what's the corresponding proposal for primitive streams? I would hate to force boxing onto users of:

Integer x = intStream.filter(...).findFirst(); just because we don't have an int sentinal we can use.

the main issue with this code is that people can write int x = intStream.filter(...).findFirst();

a will get a NPE without knowing why.

If we're going to do this to people, we might as well give them a null-safe box (OptionalInt) rather than an accident waiting to happen.

I prefer int x = intStream.filter(...).findFirst(() -> 0); or int x = intStream.filter(...).findFirst(() -> throw new WeAreInTroubleException());
