Lovely to see Racket being used. Given the pure meta-ness of Racket hopefully ydiff will not only evolve into a full-fledged version control system but a completely configurable one at that, akin to the power of Emacs and it's Lisp. Having something like a .yinrc where I could quickly throw around and test out custom functionality would be awesome. I haven't gotten much into git's plumbing yet, but I don't see a culture of hacking it like Emacs and Vim, and I'm not sure why that couldn't be. There's definitely a need, since you have things like git-flow. With structural versioning I think the possibilities of customization and automation would be greatly expanded, and I'd love to be able to use an .*rc file like I use my .vimrc daily, as a scratchpad for small scripts or for fleshing out rough ideas into later externalized plugins.

That's why I love Mercurial. The API is great, people build great things with it, and it has a policy of "default to sane, simple and working; let users tweak stuff easily".

In my experience, git has that culture of hacking, but it isn't as visible. Things get added to the "contrib" folder pretty quickly; but few ever get the polish to graduate out. On my box, contrib is installed at `/usr/share/git/`.

Just create an executable named git-WHATEVER and put it somewhere in $PATH (or $GIT_EXEC_PATH).
