Source docstring:

Splits string on a regular expression. Optional argument limit is
the maximum number of parts. Not lazy. Returns vector of the parts.
Trailing empty strings are not returned - pass limit of -1 to return all.

(defn split
  ([s re]
     (split s re 0))
    ([s re limit]
     (discard-trailing-if-needed limit
       (if (identical? "/(?:)/" (str re))
         (split-with-empty-regex s limit)
         (if (< limit 1)
           (vec (.split (str s) re))
           (loop [s s
                  limit limit
                  parts []]
             (if (== 1 limit)
