I'm sure if you used K for a year or so, that would be obvious and understandable at a single glance. But all I can think of is that I used to see that in my terminal session right after my modem got disconnected.

Been doing k for a bit (under a year). A single glance is optimistic, but probably only took me a few seconds. Almost certainly faster than any equivalent code in any other language. It's even easier if you give it a nice name, like "fib".
