Hi @eligrey. I had a question about this shim vs. the one in your blog post from 2009. Is there any reason you would include or omit the configurable or enumerable attributes?

It seems they are not actually used in IE8 (according to MSDN--see the "Requirements" section), though I've also heard it will throw an error in IE8 if you set enumerable to true. I'm just wondering if the blog version omits those attributes for this reason, or if the version here includes them as an afterthought?
