The memory management of Objective-C takes a little getting used to
if you come from an environment where you have to track everything.
If you get it wrong in Objective-C, bad things will happen
(somewhere, some day). If you get it right, then *nothing*. There is
no positive reinforcement that you have mastered the art.

As a relatively unexperienced mac developer, I wrongly assumed that

I still don't master referencecounting and thus believed that having
a check to ensure things were good would help me to detect when
I had screwed up refcounting. Long story.
Understood -- this is a common pattern of misconception.
I was sure that this was covered in the documentation somewhere,
but can't find it (modulo the comment in the retainCount method).
There needs to be a section somewhere that makes it clear that
approaching memory management like this is almost always going to
result in confusion and frustration. Perhaps you could identify
where in the documentation you would have been most likely to find
this mentioned, and file a bug report (<http://
bugreport.apple.com>) to have it included...
