Please check correctly: CORBA/raw interfaces without name do still compile,
just like Com interfaces without GUID do compile, however you can no longer
use "as" to convert a class to such an interface.

a) this is consistent with the behavior of casting such an interface to
string (you also can't use "as" to convert to a COM interface without GUID)
b) it could lead to subtle errors if a class implements multiple such
interfaces, cause TObject.GetInterface will pick the first matching
interface by name which without name will simply be the first one without a
name.
