  Example: Anything that printed out something anywhere automatically generated a hyperlink to open an inspector on the underlying objects. No additional coding necessary. The facility was provided through around inheritance in MOP.

    Right, and now Swank/Slime does this. Not to mention whatever Eclipse does for Java, etc., etc.

      As I understand it, with Genera you could inspect that all the way down to the kernel.

      Really? The actual runtime objects? Not the source code of the script, the exe file, or anything hokey like that but first class Objects as in OO and the particular instance that was sent the print message?

        You're confusing interface and implementation. You can inspect objects and click links to follow the object graph, and you can change the objects as you like while the program is running. An around modifier, IMO, is a terrible way to implement debugging functionality, because now everything that's not debugging also gets the side-effect that the method modifier adds.
