Hi folks,
I seem to regularly find myself writing ->> threaded code that follows
similar patterns:
(->> things
(map wrangle)
(map pacify)
(filter effable)
(map #(aggravate % :bees :sharks))
(reduce mapinate {})
i.e. all stages of the code actually operate on a collection rather than a
single value - usually with a call to "map" at each stage. This example is
over simplified - often many of the calls to map are inline functions,
which makes this even more verbose.
I wonder if there would be value in (yet another) variant on '->' that
assumes you are threading a collection and calling 'map' by default. I'm
not sure of the syntax that would work though. Something like:
([]-> things
wrangle
pacify
[:filter effable]
(aggravate :bees :sharks)
[:reduce mapinate {}])
I'm not sure about the syntax for non-map functions, I'm not even sure if
this is worthwhile. Thoughts?
