10 years is generous paternity leave. :) Seriously though, no hard feelings, separating the wheat from the free software chaff takes time--ask me how I know.

That interests me!
IME, I have found S-expressions to be an elegant, succinct way of expressing geometric models (especially in the F-rep domain):
I wrote a referencing counting C++ reader/writer for S-expression models like that directly into Open Inventor, in place of the IV (VRML) format, avoiding the use of CL.
Emacs has a C FFI, IIRC, so it should be possible to develop a S-exp formatted BRL-CAD model in elisp, with the right C shims--giving a live-coding, REPL experience for building BRL-CAD models.

Thanks for your work on BRL-CAD!
