Sorry I was unclear here. I meant that in FE the JS code has to work 
with older browser tat don't support loading of JS file via JS. I did 
not talk about renaming of functions.

My idea was to turn all current t3lib/xxx.js files into stubs and move 
them into t3lib/js/. Works like this (for backwards compatibility):

function myloaderfunction() {
  var el = document.createElement("script");
  el.src = "typo3/js/xxx.js";
  el.type = "text/javascript";
  document.getElementsByTagName("head")[0].appendChild(el);
}

if (window.addEventListener) {
  window.addEventListener('load', myloaderfunction, false);
} else if (window.attachEvent){
   window.attachEvent("onload", myloaderfunction);
} else {
   // ouch! won't work on old browsers incl. IE on Mac
}

In 4.3 we can remove the stubs because we announce it explicitly that we 
are about to move some files.

Problem: the files ar now loaded after the body has loaded. So anyone 
including the stubs via the HTML script tag may be surprised that the 
file's content isn't available instantly as it might be expected.
