ES4 also standardizes Date.parse to accept the same ISO 8601 date  
strings, so I don't believe any information is lost.

You're right that this automatic encoding of Date objects as ISO  
strings does not result, when decoding, in Date objects again.   
Fixing that would require a pass over the decoded structure, or a use  
of the optional object hook on the enclosing object.  Is this a problem?
