I don't think that typeof(null) should be 'null'.
If the type of an integer instance is the integer type and the type of
a string instance is the string type, then the type of null should be
the null type, not a null instance.
I suppose that you could consider that what JavaScript is doing is
equivalent to saying in Python that:
None = object()
like you sometimes do when you want a unique sentinel because None
itself would be an acceptable value.
