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 syntax in examples. I don't really like Rust's `assert(inc(1) == 2)` syntax, I find it a little distracting. I'm trying `inc(1) //-> 2`. The comment is rendered differently, and there's nothing before the sample code. What do you think?

Further tinkering with diagnostics, following feedback! * Two lines of context above and below now. * The caret is included in the line below where possible. * Syntax highlighting of keywords. I kinda feel that smart context sizing would be better. What do you think so far?
