@nikitonsky Yay. I’m a fan of a small set of reasonably well-known math conventions eg. Δx, ε, x’, x’’ on the grounds that more code on the screen at once helps me keep more context when I’m reading it.

(More of a clojure thing though. Maybe it’s the let-block culture. Somehow `delta-x` in scheme seems fine, but it could be that I’m so mentally engaged in matching undifferentiated parens I don’t notice that it could be better).
