I completely agree. Here are some of my thoughts about comments.

Wow this is a pretty cool game. A bit confusing to learn though.

That is fine with me. Good luck with the book.

Tom, I’m writing a chapter on custom controls in the forthcoming “More Cocoa Programming for Mac OS X”, and I used this code as a starting point for making a control bindable. In the end, my code looks a lot like yours. Is this OK with you?

Comment on For those who have never used Objective C by Erik

It’s a great improvement over C/C++, but Python goes even one better – you can supply the named parameters in any order when invoking the function/method, you don’t have to supply all of them (functions and methods can declare default values for any unsupplied parameter), and you can define functions and methods that take named parameters that don’t exist until they are called – the function body just gets a dictionary that contains whatever name/value pairs were passed to the function. It would be very cool to have this much power in Objective-C.

Comment on Coding Tip: Have A Single Exit Point by Tom

Strict adherence to the rule can result in complicated nested ‘if’ statements, as the article already mentions, but only in certain cases and there are ways around it.

It’s an old concept that most people should have heard of by now, but it’s hardly a “dated” concept. I don’t think most people would agree that you can throw return statements anywhere without consequences.

The problem with single exit it that it often results in less-readable code because of the complex if/else structure to channel the execution to a single exit point. It’s basically a dated concept.

Thank you. I’ve been scratching my head for a while about this and of all the examples I looked at yours was the easiest to understand.
