Objective-C - the language

First off, I read the Objective-C Primer and Objective-C Programming Language guides. I collect languages, so there was some underlying familiarity there. Ruby, Smalltalk and C obviously shone through for me. Second off, I re-read Smalltalk Best Practice Patterns. I first read that book maybe 6 years ago and it had a massive impact on my Java style. Objective-C is the most Smalltalk-like language that the 'masses' will actually use professionally. Sadly, it's not enough Smalltalk for me, and the C abstractions leak quite a bit.
