I think the reasoning is tat people use || as a string 
right now.  So if we want to allow doing | = 200| and at 
the same time allow people to treat as a string, then it 
needs to be string-like in some sense.

I suspect that just having it toString to the string it is right now is 
not sufficient for web compatibility.

Because we're trying to extend a legacy API which currently uses 
strings, not designing in a vacuum.
