==Objective-C Example== Well I don't know Objective-C, but looking at [[Copy_a_string#Objective-C|the examples]] isn't there an error on this line:

NSString *newMutable = [original mutableCopy];

shoudn't it be this below ?

NSMutableString *newMutable = [original mutableCopy];

:Well, it's not wrong -- since NSMutableString is a subclass of NSString -- it just makes it less useful. --[[Special:Contributions/|]] 05:34, 18 November 2009 (UTC)
