  done <- work_with_cache()
  print(.libPaths())
  # install.packages("cowsay") # install cowsay to your lesson cache
  # cowsay::say() # hello world
  # detach('package:cowsay') # detach the package from your current session
  done() # finish the session
  # try(cowsay::say()) # this fails because it's not in your global library
