I completely agree: If it is ugly-as-sin-but-useful I will learn it.

The aesthetic of mathematics as it appears in journals is I think questionable, but undeniably convenient for communication, so it is every language making the case that you (dear reader) can say something very complicated and useful in the ideal amount of space.

"Hello world" isn't that: That's the one program everyone should be able to write correctly, 100% of the time. That's how we can talk about brainfuck as exercise, but APL is serious.

Or put another way, even if seeing a new kind of "hello world" excites dear reader, it's probably not going to excite me, unless it's objectively disgusting.

What Om does here is exactly right for me: It tells me what it is, and makes it easy for me to drill down to each of those things to figure out what the author means by that, and decide if I am convinced.

I mean, that's the point right? I'm here trying to learn something new and that requires I allow myself to be convinced, and since "hello world" is table-stakes, seeing it can only slow my ability to be convinced.
