alt Hacker NewsThey're function calls right? I can't square the "message passing" conceit (implying putting message objects on queues, dequeuing etc) with the claim that Obj-C is just C with some extra stuff.

Absolutely not. It only sends a message. The receiver doesn't have to have a corresponding method and can do with that message what it will. Objective-C is a 'true' object-oriented language, like Smalltalk.

They're not direct function calls, but sugar for objc_msgSend():
