why inject with document.body.appendChild

[robbiemu]

this is a question not a bug.

Why does the yt.js inject code like <script>foo</script> into the document with document.body.appendChild ? Isn't there some way to directly use that code like:

      var fileref=document.createElement('script')
      fileref.setAttribute("type","text/javascript")
      fileref.setAttribute("src", filename)
      document.getElementsByTagName("head")[0].appendChild(fileref)

Sorry the previous answer was a ton of rubbish. I have made similar changes to what you suggest here.
