  # empty args style:
  test2 () {

  # you can add empty args to the keyword style: 
  function test3 () {

  # but you must have the empty args without the keyword,
  # this does not work in bash or sh:
  # test4 {
  #   echo "test4 called"
  # }
  # test4

  # i kinda like the function keyword style 'cause i don't think you can
  # put argument names in the empty args list, so it's kinda confusing
  #
  # doesn't work:
  # test5 (X, Y) {
  #   echo $X
  #   echo $Y
  # }
  # test5 "hey" "ho"
