Having parts of a string perform operations on a container is not elegant, it's a crutch for the lack of availability of generic operations or something like LINQ. Many of Objective-C's interesting features have this problem that either they're too magical, have an odd syntax or are leaky abstractions due to the limitations of backward compatibility.
