Sorry, I was at Fosdem sunday morning but not sunday afternoon (I've planned to 
visit the city with my girlfriend :-)
I've seen NSObject has changed but found nothing about accessing GS[GS]etValue 
externally. Is it possible to have this
kind of thing soon ?

Here are additional methods :
NSObject :
        - (void)takeStoredValue:value forKeyPath:(NSString *)key
        - (void)takeStoredValuesFromDictionary:(NSDictionary *)dictionary
        - (NSDictionary *)valuesForKeyPaths:(NSArray *)keyPaths

NSArray:
        - (id)valueForKey:(NSString *)key
        - (id)computeSumForKey:(NSString *)key
        - (id)computeAvgForKey:(NSString *)key
        - (id)computeCountForKey:(NSString *)key
        - (id)computeMaxForKey:(NSString *)key
        - (id)computeMinForKey:(NSString *)key

NSDictionary:
        - (id)valueForKey:(NSString *)key
        - (id)storedValueForKey:(NSString *)key
        -(id)valueForKeyPath:(NSString*)keyPath

 NSMutableDictionary:
        - (void)takeValue:(id)value forKey:(NSString *)key
        - (void)takeStoredValue:(id)value forKey:(NSString *)key

How can we integrate them into base ?


Additionaly, there some new methods in Apple doc but I haven't code for them:
        NSArray 
(http://developer.apple.com/techpubs/macosx/Cocoa/Reference/Foundation/ObjC_classic/Classes/NSArray.html)
                 - exchangeObjectAtIndex:withObjectAtIndex:
                Operators related methods (I think they are related to 
computeXXXForKey:(NSString *)key)
                        
http://developer.apple.com/techpubs/webobjects/WebObjects_5/FoundationRef/Java/Classes/NSArray.html
                        
http://developer.apple.com/techpubs/webobjects/WebObjects_5/FoundationRef/Java/Classes/NSArray.html#//apple_ref/java/clm/NSArray/setOperatorForKey
