Is all-csv-rows being re-bound with the results of [] and then
returned as the function's value? And again, thanks. This is exactly
what I was looking for.
(defn ret-params
"Generates all q-parameters and returns them in a vector of
vectors."
[all-csv-rows]
(reduce
(fn [param-vec one-full-csv-row]
(let [q-param (zipmap accumail-url-keys one-full-csv-row)
accu-q-param (first (rest (split-at 3 q-param)))
billing-param (first (split-at 3 q-param))]
(conj param-vec [accu-q-param billing-param])))
[]
all-csv-rows))
