e.g. NSCFType is not a subclass of NSCFString nor implemented in the
same file, thus the call to CFStringInitialize should be moved to
NSCFString +load.
that documentation doesn't seem to say you can't call objc_getClass(),
apparently you cannot... so the NSNull I added is broken also, its
just not crashing.
it's of the "In particular, the following things, even if they can
work in a particular case, are not guaranteed:" variety.
those were the 2 things that popped out at me looking through
CF*Initialize but i'm not all that familiar with the library.
