> no languages with mutable state that I know of offer concurrent integer and concurrent structs Java does for integer http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicInteger.html http://docs.oracle.com/javase/8/docs/api/java/util/concurren... You can find similar classes in the java.util.concurrent.atomic package. http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/package-summary.html http://docs.oracle.com/javase/8/docs/api/java/util/concurren... I'm not sure what requirements you have for a concurrent struct, but Java has classes to atomically manipulate int and long fields of a class. I'm not arguing your general point (in fact, I agree with it), I'm just supplying some extra information of a language that you apparently don't know.
