If there a reason why transducer functions are always a function? I mean this kind:
(defn no-arg-transducer []
(fn [rf] ...
(fn ([]
Why isn’t this def instead of defn, seems like there is no state there outside the outer (fn [rf]…?(source cat) shows an example along your thinking.
it’s a function but it takes the rf
Hm I don’t quite understand what’s the deal with preserving-reduced function there
oh it double wraps it
Most such cases are transducer arities for reduction functions (e.g. distinct)
I see it now, thanks
