    Web application programming, the client-side, scripting heavy
    sort that people are flocking to today, is a path that forces
    successful application developers to abandon objects.

    JavaScript is a weak OO langauge, since it lacks inhertience,
    and polymorphism. There are no namepsaces, so modular programing
    is difficult. Reuse is already hard enough to coordinate, see
    how far you get without package/unit/library facilities in the
    host language.
    Programmers will buy into the textbook notion that you can work
    around this with JavaScripts prototypes, but soon find that they
    have poorly organized, bloated classes.

    And then, of course, the OO facilities in JavaScript are slow.
    JavaScript handles many small objects, the natural direction of
    OO programming, very poorly.

    I've done some hacking on Mozile, a CSS editor that's built on
    Gecko. It followed a familiar path in development.

    In 0.6 they attempted to create an cross-browser abstraction
    layer, so that the editor would work on IE, Mozilla, and Safari.
    This never happens, and it didn't happen. The editor only ever
    worked on Gecko, and because of the extra layer, it worked

    In 0.7 the editor is written directly to Gecko. It's functions
    only, manipulating the DOM. 

    There is a natural direction from this realzation, is toward and
    application that application uses closures to specify editor
    behaviors, which, since they are used in all scripted event
    handlers, are vetted, and perform quite well.
