Is Objective-C discussed at all?

Only as a brief aside (don't have the timestamp right now) to talking about Smalltalk, which he mostly discusses to argue that Smalltalk was not different from C++ in seeking (most of the time) to model programs in terms of static hierarchies (according to the primary source documentation from the time of Smalltalk's design):

Objective-C is basically Smalltalk retrofitted onto C, even more than C++ was Simula retrofitted onto C (before C++ gained template metaprogramming and more modern paradigms), so it makes sense that Muratori doesn't go much into it, given that he doesn't discuss Smalltalk much.
