> Recently it was found that we could add multiple overrides of a method where it was using a FunctionalInterface but also make that interface extend Serializable.  This would allow for provided lambdas to be instantly serializable since the JVM will pick the most specific argument.
> Example:
> {code}
> CacheStream filter(Predicate<? super R> predicate);
> {code}
> vs
> {code}
> CacheStream filter(SerializablePredicate<? super R> predicate);
> {code}
