There's no good reason there *should* be anything about that in this method
description. The same standard pattern that's applicable everywhere and
*thoroughly* documented applies here too:

Your assumption is flawed. Anyone who tries to use reference material as a
tutorial is learning Cocoa the hard way. It's like trying to learn English
from a dictionary, and your proposed "solution" like including a
grade-school grammar introduction with dictionaries.
Further, the class documentation is intended to document the NSArray class,
including any exceptions to the standard Cocoa conventions and patterns. It
is specifically and by design *not* intended to document universal patterns
that apply to every class and method. The documentation writers didn't
intend to write the docs your way and fail to do so, they intended to write
it the way it's written.
