Oh, something like LispWorks has extensive support for using images, too. It has a very extensive application/library delivery mechanism based on images.
LispWorks can also save 'sessions', even automatically as periodically timed events. Even without quitting Lisp. Sessions are basically IDE states (files, listener history, lisp image, windows, ...).
In any case, at least a few Schemes have images, so it's a moot point in that debate. It's still interesting, though.
