Just a quick sense checking question, since I can't find much
info/examples about this:
Is this use of `eduction` the most efficient and/or idiomatic way to
create a 1:N mapping? I.e. in the example below for each value in
`cells` N transformed values are created...
Could this be also achieved via comp'ing the transducers? (I can't see
how at the moment...) But if so, are there any penalties w/ using
`eduction`?
;; cells = vec of ints (vector indices)
;; kernel = vec of ints (index offsets applied to each cell index)
(into #{} (mapcat (fn [i] (eduction (map #(+ i %)) kernel))) cells))
Thanks, K.
