Frequent contributor Argle Bargle (recently, or even in last week's Errord) works with a programmer called "Jimbo". Jimbo is a solid co-worker and a good programmer. He has more tenure at the company than Argle, which means Jimbo is who Argle goes to when he has questions.

Much of its functionality was opaque and complicated, so Argle wrote literal paragraphs of documentation explaining what the code did, how to invoke it, what the gotchas might be, and how to avoid them.

We get a fair bit of it in our inbox, and we generally don't post it often, because, well, it's usually just a sign that someone generated the code.

We know 2026 is not a leap year. But how do we know that? We need to call some function to find out.

Steve sends us a bit of representative code; on it's own, it's not so bad, but with the broader context, it's horrifying:
