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.)

Caddy is really growing on me. It's nice having a web proxy that includes letsencrypt functionality without any additional configuration. I've tended to use nginx with a separate letsencrypt setup for projects before, and it's much more awkward.

I'm experimenting with diagnostics formatting. * I've added a left margin, showing both the file name and line numbers * I'm showing one line of context above/below the offending line. * I'm using grey for comments. What do you think? Is there anything you'd change?
