Compiler error messages is such a deep topic. Even in rustc, a mature compiler that invests effort in diagnostic quality, I find interesting issues every few months. (The majority have been fixed pretty quickly, so it's really rewarding to file issues.)

There's something pleasingly self-referential about configuring an agent by talking to it. > Remember that [fact about data formats]. Agent: Noted. ... realise nothing happened ... > Write to your rules file that when I say "remember", I want you to write to the rules file.

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?
