Summary:
Presently, there is no way to safely and quickly retrieve the first object in an array/collection. `objectAtIndex:` throws an exception if you request an out of bounds object, whereas `lastObject` safely does what it says on the box.

Given how common it is to request the first object in an array, I'd love to see a simple addition to these guys:

-(id)firstObject
{
    if ([self count] > 0) {
        return [self objectAtIndex:0];
    }

    return nil;
}

Any chance of that happening? I'll file the same against the iOS SDK.
