and 96% of it is pure functions

Thanks - I was just wondering how this somewhat precise statistic was obtained.

Otherwise, all that makes sense generally, though I tend to model logging as an effect in statically typed languages with effect systems. But I agree that it isn’t the most important thing!

As an FP-fan interested in Clojure, how does one track if functions are pure in Clojure? I had assumed this was not possible, due to it not being statically typed (although I gather there is 3rd-party support for gradual typing).
