It will be inconvenient to use transducer functions without the transducer
support added in 1.7.0, but there's nothing magical about transducers that
requires Clojure 1.7.
Core.async 0.1.346.0-17112a-alpha does not depend on clojure 1.7 (it only
depends on Clojure 1.6) and you don't need anything special to create a
transducing function. We use the transducer features of core.async with
Clojure 1.6 in production.
All you need to do is provide the core async channel with a function that
has the transducer structure: a function accepting a transforming-function
(supplied by core.async) and returning a function with three arities for
initialization, finalization, and the reduction step.
(fn [xf]
(fn
([] (xf))
([r] (xf r))
([r v] (xf r v)))
We use an as-transducer function as a convenience to make these:
