title: How to pull out every comma, hyphen, underscore, space, and joining remaining words without spaces?
body: <p>I guess this would be a rather long regular expression, but is there a way to takeout underscores, spaces, commas, and hyphens from a string and then join the words together in perl? </p>
  
  <p>Example:</p>
  
  <pre><code>_Car - Eat, Tree
  </code></pre>
  
  <p>Becomes:</p>
  
  <pre><code>CarEatTree
  </code></pre>
