No, and I was thinking at the time that it would be pretty easy to make Deprecated into some subclass of Warning which uses some string concats to compose the message. Upon further reflection, however, that may not be a good idea. What we'd like I imagine, eventually, is to be able to predicate the warning on the frontend's -Wno-deprecated state.
