Scribble library for exam creation?

I'm still using an ancient exam construction framework based on (a) a bunch of relatively simple TeX macros that I got from Matthias, (b) Dorai Sitaram's slatex, and (c) a cheap-hack scribble language that expands into TeX. These are all somewhat fine, and I know their ins & outs pretty well, but there are a bunch of hacks (added a new one yesterday!) that I could probably cut from this tower if I were using scribble directly to PDF. Has anyone here used scribble for exams? If so, any code you'd be willing to share?
