No init value given with transduce uses the zero arity value of f rather than the zero arity of the reducing function through xform:
With Clojure 1.7.0-alpha2: user=> (doc transduce) ------------------------- clojure.core/transduce ([xform f coll] [xform f init coll]) reduce with a transformation of f (xf). If init is not supplied, (f) will be called to produce it. user=> (transduce println-transducing-fn + [1 2]) two arity two arity one arity 3 user=> (transduce println-transducing-fn + []) one arity 0 On Tuesday, September 16, 2014 7:48:51 PM UTC+2, Ghadi Shayban wrote: > > Call 'transduce without an init value, and it will use the 0-arity return > as init.
