Apple do not seem to be even _considering_ OpenStep. The new stuff they've
created has a rather different API style, and the new classes are
substantially overengineered when compared to the OpenStep philosophy (and
the Unix philosophy, for that matter).

Apple's Foundation is based to a large degree upon CoreFoundation, a C
library. This is one of the reasons Apple's Foundation is so slow, and a
reason why it is not a direct descendant from OpenStep.
