title: JavaScript getter for all properties
body: <p>Long story short: I'm in a situation where I'd like a PHP-style getter, but in JavaScript.</p>
  
  <p>My JavaScript is running in Firefox only, so Mozilla specific JS is OK by me.</p>
  
  <p>The only way I can find to make a JS getter requires specifying its name, but I'd like to define a getter for <em>all</em> possible names.  I'm not sure if this is possible, but I'd very much like to know.</p>
