Handy for someone (like >> me) who has multiple Emacs versions. By the way: you might want to reconsider your use of function overrides in your *+.el packages. That's about the riskiest possible thing to do from a compatibility perspective, and it's impossible to maintain compatibility with packages that work like this. I know you want to run on older versions of Emacs, but it'd be better to contribute these changes to the core.
