Mini experiments with Java lambdas

I dusted off some Java 8+ Lambda code snippets I had on my Github Gist. I watched a few JVMLS videos this month and found myself struggling to grasp the internals of MethodHandles and everything related.  So, I thought I should spend some time at least looking at the code it generates.


Until next time!
