I would rather specify exactly how the property behaves, i.e. as a 
writable data property.  As I mention in the bug, the global will need 
to be a proxy due to its named properties etc. anyway, at which point 
you can perform your optimisation as part of your proxy traps.

I won't be making any change to the spec here.  For the Disposition of 
Comments document, could you please indicate whether this resolution is 
satisfactory or not.

Thanks,
