My #Java single-threaded concurrency solution is currently able to switch between tasks around 75-80 million times per second - on my 6 year old laptop. I guess that's enough for a lot of use cases. I still need to tweak the design a bit + add features, so the number may change.

Came across an interesting #Java compiler riddle while exploring the Apache Flink code base; what happens when compiling this code?
// in package a public class Outer { private static class Inner { @FunctionalInterface public interface Supplier { int getInt(); } } public static void invoke(Inner.Supplier supplier) {} } // in package b import a.Outer; public class Reference { public static void main(String[] args) { Outer.invoke(() -> 42); } }
