Yes; in any method, self is (or at least starts life as) the object which
received the message.

I don't think that would work for class clusters. Consider +[NSArray
array]:
#import <Foundation/Foundation.h>
int main (int argc, char ** argv)
{
id arp = [[NSAutoreleasePool alloc] init];
id array = [NSArray array];
NSLog(@"%@", NSStringFromClass([array class]));
[arp release];
return 0;
}
intel:trunk leeg$ ~/foo

so it doesn't return the class in your case 1, which would be NSArray. It
doesn't return the class in your case 2 which would also be NSArray ;-).
