This is not safe usage, as you are not calling the 'flushing' method
or handle reduced objects. Correct use would be
(def xform (comp (filter odd?) (map #(* % %
(def strip-reduced [x] (if (reduced? x) @x x))
(let [r (xform conj)] (strip-reduced (r (strip-reduced (r #{1 2 3}
7) ;=> #{1 3 2
Some alternate transducers usage:
(def xform (comp (filter odd?) (map #(* % %
((xform conj) #{1 2 3} 7) ;=> #{1 3 2 49}
((xform conj) [1 2 3] 6) ;=> [1 2 3]

Oh dear, I still haven't understood the blogpost on reducers yet, and
now there is this one as well.

Thanks Rich!
Transducers, like all of your releases, are an eye opener.
I've always felt slightly hesitant to use core.async's version of sequence
functions, because of the overhead of intermediate channels. Then there was
the strictness tradeoff with reducers. All of that complexity, gone from m
th it for sure.

This work builds on the work done for reducers, bringing context-independent
mapping, filtering etc to other areas, such as
