I don't think that meaningfully engages with the author's point. If you already know how to compute `len` on some arbitrary syntax soup then the difference is just a minor annoyance where you have to jump back in your editor, add a function call and some punctuation, and jump back to where you were to add some closing punctuation. It's so fast you'd never bother with an LLM, so despite real and meaningful differences existing the LLM discussion point isn't relevant. If you don't know how to compute `len` on some arbitrary syntax soup, I don't see how crafting an ideal prompt in a "full (very isolated) context" is ever faster than tab-completing things which look like "count" or "len."
