Oh. I can't even really use this. I don't know what I need to associate at
runtime, at which point I know what it is by a string value. Since I can't use
a string value as a key, I can't really make the association. I could associate
an NSMutableDictionary, but if I do that, I may as well just m

I think you can only use class_addIvar() in between corresponding calls to
objc_allocateClassPair() and objc_registerClass().

I'm trying to add an ivar to a (sub)class in the base class' +initialize
method. I'm not sure if it's too late to do it at this point or not. If I can't
do it here, i don't know where to make the call.
I'm calling it like this:
char const* ivarNameCString = ivarName.UTF8String;
