title: Equivalent of the Scala IDE worksheet in other languages?
body: <blockquote>
    <p>A worksheet is a Scala file that is evaluated on save, and the result of each expression is shown in a column to the right of your program. Worksheets are like a REPL session on steroids, and enjoy 1st class editor support: completion, hyperlinking, interactive errors-as-you-type, auto-format, etc. (source <a href="https://github.com/scala-ide/scala-worksheet/wiki/Getting-Started">https://github.com/scala-ide/scala-worksheet/wiki/Getting-Started</a>)</p>
  </blockquote>
  
  <p>Is there anything similar in any other language? I mean, I know about REPL in other dynamic languages, but what the worksheet does s much more.</p>
