Well firstly you can just type keywords and they get swapped by glyphs
Secondly, the power with Uiua is you can easily split up that expression literally by just hitting enter in some spots (and line swapping but…). You can give names
And finally if you are constantly doing operations across arrays it can be more legible to go a symbol like approach, like how most people prefer x+y to add x y. The conciseness helps you build up larger expressions before you need to break things up.
