Hi Ernie,
"Many" in this case refers to "N", which is "0 ... N",
OK, I was wondering about "many" including "0".
so I'd say while it is techincally correct as-is, perhaps more precise
would be to say "1-to-0..1" gatherer, since for every element in,
there is 0 or 1 element out.
I see.
Many-to-one would be 0..N -> 1, which means that an empty input would
"could" not "would"?
yield a single output.
Out of curiosity, is either correct technically?
Other than at initialization or finish, is it possible to have an
"empty" input?

This is about what might be a minor doc issue.
In https://openjdk.org/jeps/473 <https://openjdk.org/jeps/473> it says
As another example, |Stream::filter| takes a predicate that
determines whether an input element should be passed downstream; this
is simply a stateless one-to-many gatherer.
Shouldn't this be "many-to-one"?
