--- Comment #10 from Kenji Hara <[email protected]> 2011-10-15 02:55:26 PDT --- https://github.com/D-Programming-Language/druntime/pull/72 (In reply to comment #8) > 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). > 2. how does an opEquals defined in an interface interact with the > object.opEquals? An interface's opEquals is not used directly. Object.opEquals is always used for the interface comparison when it is possible. > 3. a forced cast, unlike an implicit cast, is a blunt instrument that can do a > lot more than simply cast an interface to its base class. If the arguments are > other types, what are the conseqences of this forced cast?
