title: perl assign string on multiple lines
body: <p>I'd like to be able to assign the concatenation of multiple strings to a variable.</p>
  
  <p>I'm looking for something like this:</p>
  
  <pre><code>$variable = 123
  $string = "hello" +
            "this is a " +
            $variable +
            "string";
  </code></pre>
  
  <p>Is it possible to do something along these lines in perl?</p>
