In a recent thread on lemmy, it
was asserted that 96% of the code (or functions according to the post) in Pedestal is pure. I'm curious if anyone knows the reference for this, or how one would obtain this metric for Clojure code. I'm not (yet) a Clojure programmer myself, but just started learning. However, I'm interested in knowing how this is done, not only for Clojure, but more generally for the JVM at large.
