Theoretical and Practical Weaknesses of Objective-C
Objective-C is a compromise by design, and it is utterly unembarrassed by this. It is, I think, a good compromise, finding a sweet spot where one has very convenient access to low-overhead constructs for performance (C and C++ can be linked in and even intermingled with ObjC) while still having a nice dynamic messaging system supporting flexible late-bound polymorphism.
It’s also a compromise from the ’80s. (Relatively) recent advances in functional programming (among other spheres) sometimes make me wonder if we could strike a better one today.
