title: Examples of using some Scala Option methods
body: <p>I have read the <a href="https://tonymorris.github.io/blog/posts/scalaoption-cheat-sheet/" rel="nofollow noreferrer">blog post</a> recommended me <a href="https://stackoverflow.com/questions/6819373/why-is-foreach-better-than-get-for-scala-options">here</a>. Now I wonder what some those methods are useful for. Can you show examples of using <code>forall</code> (as opposed to <code>foreach</code>) and <code>toList</code> of <code>Option</code>?</p>
