We did discover that default methods on FIs combined with subtyping of
FIs caused trouble. But static methods are fine.
If we're going to do Xxx.of(...), we should do it uniformly across FIs,
not just for Predicate. I think this is a reasonable move, but we don't
have to do it right now. (T

+1 thank you for taking action on this.
Predicate not captures
Actually it would be:
Predicate.of(String::isEmpty).negate()
But
not(String::isEmpty) reads almost like !str.isEmpty()

Hi Jim,
Have you thought of introducing something like:
static Predicate Predicate.of(Predicate target) {
return target;
}
instead?
I think that might allow you to do things like:
Stream.of("", "A", "b", "c")
.filter(Predicate.of(String::isEmpty).not())
.filter(Predicate.of(
