===[[Objective-C]] (Cocoa/GNUstep)===
[[Cocoa (API)]] and [[GNUstep]] handle associative arrays using <code>NSMutableDictionary</code> (a mutable version of <code>NSDictionary</code>) class cluster. This class allows assignments between any two objects to be made. A copy of the key object is made before it is inserted into <code>NSMutableDictionary</code>, therefore the keys must conform to the <code>NSCopying</code> protocol. When being inserted to a dictionary, the value object receives a retain message to increase its reference count. The value object will receive the release message when it will be deleted from the dictionary (both explicitly or by adding to the dictionary a different object with the same key).
