title: Using Underscore's _.throttle in a function declaration
body: <p>I'm curious as to why wrapping a function with _.throttle does not work in a function declaration. This function expression behaves as expected:</p>
  
  <pre><code>var myFunc = _.throttle(function(){
     console.log("I'm throttling");
  }, 1000);
  </code></pre>
  
  <p>Though this does not:</p>
  
  <pre><code>function myFunc(){
      return _.throttle(function(){console.log("I'm throttling");}, 1000);
  }
  </code></pre>
  
  <p>Any insight would be much appreciated.</p>
