I don't know how you will do it -- please don't hack the engine, thereby 
creating a non-standard and incompatible dialect of the language.

If the global object (the last object on the parent-linked scope chain) 
is not where variables go, then what does go there?  If you wish to 
share standard classes (Date, RegExp, etc.), consider linking to a 
"superglobal" via the proto, not the parent, slot.
