...ly common in partially constructed states -- in your initializers and in dealloc, it's best to use direct access. You may also find this common in the implementations of an accessor, a convenience constructor, copy, mutableCopy, and archiving/serialization implementations.
It's also more frequent as...
What is external linkage and internal linkage?
