Pattern matching with https://github.com/HealthSamurai/matcho

It'd be cool to be able to do pattern matching with https://github.com/HealthSamurai/matcho instead of just comparing for literal equality.

The two main use cases I have in mind are partial matches and predicates:

(comment
  ; The return value is a map containing {:foo :bar}
  (let [big-map (apply assoc {} (repeatedly 10 rand))]
    (assoc big-map :foo :bar))
  ;=> {:foo :bar ...}

  (require 'clojure.spec.alpha :as s)

  (let [http-response-body (slurp "http://example.com")]
    {:status  200
     :body    http-response-body
     :headers {"foo" "bar"}})
  ;=> {:status  200
  ;    :body    string?
  ;    :headers (s/map-of string? string?)}
  )

For the record, as implemented, matcho assertions must follow =>> instead of the original =>, which remains an assertion of literal equality.
