And everyone else's point is that someone who goes straight to the class
reference is skipping the first half of the manual, and then (quite often)
complaining that the material they skipped isn't repeated in the second
half. That's like skipping the first semester of a foreign language class,
then demanding the teacher repeat everything in the second, so you can catch
up. It's not an effective way to learn the material, and it's an unfair and
unnecessary distraction to the students who *were* paying attention the
first time.

There's a reason the list guidelines suggest linking to the memory
management rules instead of paraphrasing them. Quite often, even experienced
developers get the summary wrong to some degree - which, I'm sorry to say,
you have done in this summary. The *correct* rules can be found here:

On what basis would someone who *hasn't* skipped the introductory material
above make that conclusion? And, given that skipping that material leads, as
you've shown here, to false conclusions, on what do you base your assertion
that skipping the introduction is a good idea?
The method you referred to above (+arrayWithObjects) is not one of those
listed in the memory management docs as requiring you to release the
returned object, and it's not explicitly documented as being an exception to
the general rule. The only reasonable conclusion that someone who' *has*
read the intro docs could arrive at is that the general rule applies -
releasing the returned object is not your responsibility.

What you're saying is not true, and the documentation correctly says it's
not true.
