What I think is the interesting part of the question is the inclusion of
the word "idiomatic". I'm not sure swiss-arrows is idiomatic... that said I
don't know what would be considered idiomatic here.a
One solution I know of for examples like this is:
(-> 2
(+ 2)
(#(* 1 % 3)))
I'm not sure this is idiomatic either, but it at least has the benefit of
requiring no additional dependencies.
