I work in a slightly different way by always saving my code in emacs and loading it fresh each session (though I have gone a couple of weeks with a live image/session on my laptop). I am fortunate that my 3D system [0] compiles and loads in a few seconds.

I also use the REPL for quick tests, and evaluate new code by writing it in emacs and compiling it one function at a time (C-c C-c).

Finally, I keep files of tutorial/demo/test cases which work a bit like a notebook, allowing me to quickly verify that existing 3D scenes still work.
