title: Using lodash to filter an object property
body: <p>I'm trying to use the _.filter property to filter an array.  I'd like to use the matchesProperty shorthand, but don't want to do a straight comparison.</p>
  
  <p>eg. This works:
      <em>.each(</em>.filter(this.across, ['len', 3]), dostuff);</p>
  
  <p>but if I want to filter values less than 9, I need to use a function:
      <em>.each(</em>.filter(this.across, function (o) {return o.len&lt;9}), dostuff);</p>
  
  <p>Is there a neater way to do this?</p>
