The clojure.core.match/match docstring states that it takes "...a vector of
occurrences, vars. Clause question-answer syntax is like `cond`. Questions
must be wrapped in a vector..."
https://github.com/clojure/core.match/blob/5429e20f5db8c398d745f15f7a85f65976f45397/src/main/clojure/clojure/core/match.clj#L1966-1976
However, it seems to work without wrapping the occurrences and questions in
vectors.
(match [{:a 1 :b 2}] [{:a 1 :b x}] x);;=> 2(match {:a 1 :b 2}
{:a 1 :b x} x);;=> 2
Is the docstring outdated or are there circumstances that necessitate
wrapping the occurrence/s and question/s in vectors?
