What are effects?

Running Example

To create instances, use this code

ex6 =>

  items := ["red", "yellow", "green", "pink"]

  something(x String) =>
    say "I saw $x elephants"

  # using a loop
  for x in items do
    something x

  # using a pipe and a lambda
  items ! something

  # using map and a lambda
  items.map something
       # map is lazy! To see side effects, force execution, eg., using fold
      .fold unit.monoid
