I have added backwards-compatibility definitions of instancetype (defined to id 
if unsupported by the compiler) and updated the collection classes I was going 
over anyways. This promptly caught two (albeit harmless) cases in base where an 
immutable object was assigned to a variable typed for the mutable subclass. 
Regarding nullability annotations, I've already added the macros for non-null 
audited sections, but I'm still a bit unsure about how to handle/define the 
nullability qualifiers, especially since there are now three variants of them 
(the double-underscore ones, the underscore-and-capitalised ones, and the 
contextual variants without underscores in method parameters). So yeah, it’s on 
my list. 

Cheers,
