Lack of warnings on [[self alloc] init] type errors

gistfile1.txt

@interface MyClass : NSObject

@end


@implementation MyClass

+ (void)myMethod
{
  NSArray *x = [[self alloc] init]; // This _doesn't_ throw a warning, despite +alloc and -init both being declared as instancetype
}

@end

[[MyClass alloc] init] correctly throws a warning in this scenario, but self seems to make the return types be treated as id.
