One of the things I like about code is that it's usually very easy to read. There are problems with characters like 1 l I 0 O i j etc that are addressed by font choices. But even with those problems I find it much easier to read the ASCII letters than math notation with subscripts and superscripts, Greek letters and script letters, bold and doubled, and so on. People might deny having the same problem, but I've seen it hundreds of times where a mistake is made because two symbols were conflated or a subscript was overlooked, or a symbol with multiple uses in different contexts was assumed to be one thing when really it was another. That said it's still neat to see code using common symbols with what you'd find in textbooks.
