I can confirm this bug, and its a nasty one (IE9 beta1 has the same issue and I've reported it to them as well).

One of our chief uses for this is the ability to 'lock' a global variable acting as a namespace for a library of code, such that it can't be inadvertently blown away by a user of that library forgetting to 'var' a variable of the same name:

Object.defineProperty(self, 'myLib', {writable: false});

Then 'myLib' can be used to 'hang' code off of, but can't be blown away.

Any ideas on fixage here?

Cheers,

- Bill
