Re: "recursive" hierarchies and derive

Leif is right, but isa?'s docstring doesn't mention this behavior. Here's the relevant code: https://github.com/clojure/clojure/blob/028af0e0b271aa558ea44780e5d951f4932c7842/src/clj/clojure/core.clj#L5120 On Tuesday, May 13, 2014 12:22:28 AM UTC-4, Leif wrote: > > Hi, Ranko. > > I *think* it's
