Any modern languages should have its REPL, Erlang, Elixir, Haskell, Clojure, Ocaml, Python... All of them got one shell-like feature to interact with the application in conception phase. That's kinda mandatory to me, it permits to test functions before adding them in the final commit, it can be used to draft quick ideas and so on. When I started learning Dart, I was a bit sad it was not integrated by default... but someone decided to fix that by creating the interactive package! Let create a new project called myrepl just to check that.
$ dart create myrepl
