I'm playing with DOT output for debugging syntax trees from difftastic. Here's an F# snippet, the Debug representation, and the DOT rendered as an image. I'm pleased with the information density on the graphic, but we'll see how often I end up using it.

I'm experimenting with jj this weekend. It seems pretty nice so far, but the mental model is pretty different from git. For example, there's no `checkout` command. You do `jj new ABC` to switch to a commit, which creates a new empty commit on top of ABC.
