I decided to ask you before submitting patch here.
It’s about objc_lookup_class generation for every class member invocation,
ios runtime generates this case OBJC_CLASS_$_classname, the same behaviour I found
in objfw (CGObjCObjFW), also it took into account attribute(weak_import).
The question is following: gnustep runtime it’s none-fragile runtime as well as objcfw,
so is it worth to emit OBJC_CLASS_ reference in that place or I missed something?
