Document.currentScript workaround

gistfile1.js

function getCurrentScript(callback) {
  if (document.currentScript) {
    callback(document.currentScript);
    return;
  }
  var scripts = document.scripts;
  function onLoad() {
    for (var i = 0; i < scripts.length; ++i) {
      scripts[i].removeEventListener('load', onLoad, false);
    }
    callback(event.target);
  }
  for (var i = 0; i < scripts.length; ++i) {
    scripts[i].addEventListener('load', onLoad, false);
  }
}

getCurrentScript(function(currentScript) {
  window.console.log(currentScript.src);
});

Awesome!
