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 not sure if I should use the term "text diff" or "textual diff" to refer to a conventional, line-oriented diff of text in difftastic. Any opinions? Which seems clearer to you?

What are the most popular languages that have used an AST walker for their implementation? I know Ruby used to do this, but there must be others. (I'm interested in the lowest PL speed that users will tolerate if you have awesome features.)
