/*
* Anonymous functions and lambdas
* Lambda are a simmpler syntax for anonymous functions.
* If Lambda has a return value -- that return is from last expression
* Lambda are usually a single expression, but they can be more
* Real power of lambda is doing things with one-off -- for instance the final print
