<pre>In the code below, I should get an error on the use of
-objectForKeyedSubscript: via the subscript operator, but I don't. This also
applies to __attribute__((deprecated)) and the various forms of
__attribute__((availability)).
@interface Subscriptable
- (id)objectForKeyedSubscript:(id)sub __attribute__((unavailable));
@end
id test(Subscriptable *obj) {
return obj[obj]; // no error here!
}
id control(Subscriptable *obj) {
return [obj objectForKeyedSubscript:obj]; // error as expected
}</pre>
