title: Line numbers in errors JavaScript
body: <p>I am looking for a way to include line numbers in the errors thrown, even if I have to do it manually - IE is terrible at this. Due to the sheer size of the code (about 180kb in advanced optimizations mode of the closure compiler), this would be really useful.</p>
  
  <p>All potential errors are already well dealt with in try catch blocks, custom errors are implemented to throw good relevant messages etc. As I am slowly preparing for production, I want to know if any of you has done this error tracking before and how. </p>
