We see hints to this model in #Java's #Optional class, with its #ifPresent(Consumer) method, and its #ifPresentOrElse(Consumer, Runnable) method.
And it's a shame that we can't apply this model to Strings or anything else implementing an isEmpty() method: the Java #programming #language won't let us #subclass most of its core classes.
It feels easier to implement this in a #trait-based language like #RustLang.
