title: Clearing Empty Strings from an Array
body: <p>I'm dealing with a bunch of arrays made of strings and many a times I've written <code>.delete_if { |str| str.empty? }</code> </p>
  
  <p>Now, I know I can add this method to the array class myself but I'm hoping there's a built in way to do this without having non-standard methods added to base classes. As much fun as adding methods to base classes is, it's not something I wanna do for maintainability reasons.</p>
  
  <p>Is there a built in method to handle this?</p>
