I found that the eduction example in clojuredocs does not work with Clojure 1.10.3
user=> (reduce + (eduction (map inc) (range 3)))
Execution error (ClassCastException) at user/eval149 (REPL:1).
clojure.core.Eduction cannot be cast to clojure.lang.IReduce
eduction does not work with reduce function anymore? or is it kind of bug?
With a default value, it works again.
user=> (reduce + 0 (eduction (map inc) (range 3)))
