Python tab completion does wonders. I know when I was messing around with blender it worked really well when I didn't want to read the code (or figure out what was missing from the API for patches).
Not too sure the "artist types" will ever get very comfortable with the command line but they can usually describe what they need well enough for a techie to code up what they need given a good enough API.
