> 1. what should happen if this is called with a COM object?
If two interfaces are identity comparable, returns its result. Otherwise,
downcast to Object, and the result is false.
And this rule also appleied to C++ interface (COM interface is C++ interface,
and the downcasting from C++ interface to Object returns always null).

An interface's opEquals is not used directly. Object.opEquals is always used
for the interface comparison when it is possible.

Same as Steven's comment in #9.
