With ASpect and bytecode manipulation, you can replace at runtime every
read/write access to a class attribute, or every calls to a method. For
example:
public class MyClass {
protected String _myValue;
protected void aMethod() {
_myValue = "Hellor world";
}
}
Now, you can create an aspect to log every access to aMethod, and to
make this class persistent by adding an attribute _isDirty and to set
it to true everytime that _myValue is updated. Two aspects that you can
add to your program separatly, but that you can reuse to another
program! For real examples, see those sites:

I don't know how to add those features in Objective-C. How can you do?

Well, what needs an explanation?
(i) Aspects are *by far* inferior to the power of ObjC/Cocoa.
If you don't think so, first implement HOM (including proper futures)
in Java with aspects -- since it is easy with ObjC/Cocoa; if you do,
I'll humbly admit I was wrong in saying (i).
