Nonsense.  You have to differentiate between `Object' and 
`Object.prototype'.

However, this was just a proof-of-concept.  Because someone at the ECMA-262 
WG could get the idea that an Object.equals() etc. could come in handy at 
some time, in a real implementation I would use my own namespace, unless the 
method definition serves as a fallback for a specified method not being 
implemented (for example, Object.defineProperty()).  One of the next JSX 
revisions will reflect that.

I am not emulating a namespace here, though.
