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?

I think you could build an interesting IDE with a tiny embedded LLM in addition to the usual tooling. Features like 'extract method' would be much nicer if an LLM could provide a name. Choosing a good name is virtually impossible from just a typed AST.

`init` feels like an unhelpful name in OO. It doesn't give you an initial value, it initialises the instance that has already been created. Developers are often surprised that init doesn't return the instance, because they have a strong association with `new Foo()`. Perhaps `finish` would have been a less confusing name?
