title: Scala - What does ' => SomeType' means?
body: <p>Today I would like to ask what does the <code>=&gt; SomeType</code> mean. I found it used in <a href="http://www.codecommit.com/blog/scala/the-magic-behind-parser-combinators" rel="nofollow noreferrer">this article</a>. It's in the part 'The Sequential Combinator'.</p>
  
  <p>Thanks for any answer!</p>
