title: Shortcut for setting initialize() args to attributes?
body: <p>This is a common initializer pattern:</p>
  
  <pre><code>def initialize(title, val, type)
    @title, @val, @type = title, val, type
  end
  </code></pre>
  
  <p>Is there a shortcut that is equivalent to "take every argument, create an attribute of the same name, and set the attribute equal to the argument's value"?</p>
  
  <p>I'm looking for a gem-free solution.</p>
