It might be worth pointing out that in Objective-C, like Ruby and unlike
Smalltalk, if-statements are not considered message sends, and so
don't/shouldn't follow the message-consuming-nil behavior; in ObjC, a nil
is treated as false in an if statement, just as it currently is in Ruby.

It's an interesting debate; in theory I side with the
exception-throwing-nil view, although I have to admit I never had any
problems with it when I did a lot of ObjC, and it lead to some
interesting idioms - for example, when writing

[mutex lock];
...
[mutex unlock]; 

these became no-ops if you were running single threaded and your mutex
was set to nil.
