We actually have one which we're considering getting rid of :)
The ones you outline are fairly low-value; they make tons of sense in a world when inner classes are your only tool, but
() -> false
is more compact and more efficient and just as clear as
Predicates.alwaysFalse()
So our approach is to mostly avoid such trivial conveniences.

Hi folks,
Have you already considered a Predicates class / static methods in Predicate with useful methods such as alwaysTrue(), alwaysFalse(), isNull() etc? Something like Predicates in Guava: http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Predicates.html Regards, Michael
