Another point is that interface objects also have to respond to [[HasInstance]]
(so that you can do `document instanceof Node`), which for native objects is
only defined for Functions.  The current Proxy proposal does not support a trap
for [[HasInstance]], nor does it have trap that would allow an interface object
implemented as a Function object to return "object" when typeof is applied to
it.  This is another issue that would prevent pure JS implementations of the
DOM, which some people want to do.
