title: debugging underscore.js templates is difficult without line numbers
body: <p>I am converting a rather large php template (page with basic logic in it) into an underscore.js template.</p>
  
  <p>The problem is that I keep having errors in it, and it's minified "compiled" version doesn't give useful information or line numbers when an error is thrown. </p>
  
  <p>Is there a way to get better template debugging in underscore.js (such as line numbers)? And if not, is there a way to get the template to terminate at a point (this way I can narrow down where the error is).</p>
