I hardly think it is fair to blame startup time. How often do you restart
your window manager? I restart mine on average once every few weeks.
Besides, X11 is pretty slow to start up. Enlightenment with the gnome
desktop takes a real long time to start and no one is bothered by that.

(not that I use SCWM, I use twm because it works and does what I want).

The ``single author'' principle is very powerful. While scheme is a nice
simple elegant language, it is not characterised by simple clean
implementations, at least, I haven't seen one yet. The result is a lot
of black magic and a long lead time for hackers. That doesn't effect the
end-user but it does make it difficult to put a project together.

Hmmm, could goops assist in handling this sort of dynamic stuff?
I mean, that is what object systems are all about (or so I thought)...
I'll admit that I don't know much about goops and have never really
caught onto the OO bandwagon.
