I've done this to myself because I was too lazy to write the `fmt!()` instead of the raw string while I was iterating and then just forgot to fix it later. I think the Go logger's default of accepting chained parameters that it logs by default to JSONL worked well to avoid that. Convenient ergonomics just in time (in the cosmic sense of programming) for it all to be irrelevant because an LLM always puts it in the error string.
