void main() {

//Here we have a perfectly valid anonymous function, however it will not output to the screen.

  (){print("Hello");};

//Next we need to build a list that will test our function.

  List people = ["Joe","Jack","Bob"];

//Here we genericly print the list with a library function.

  people.forEach(print);

    print("---------------------------");

//Here I wanted to show just what passes and definitions the function uses.

  people.forEach((name) {

    print(name);

  });

  print("---------------------------");

  people.where((name) {

    switch(name){
    case "Joe":
      return true;
    case "Jack":
      return false;
    case "Bob":
      return true;
    }

//Here we slighty tweaked the function to output only a select few of the values.

  }).forEach(print);
