Oh, that's good to know, but I'm talking other way around. Where I can
dispatch based on what the spec is for a given data-structure.
Like if I could do this:
(defprotocol Bar
(bar [this]))
(s/def ::name string?)
(s/def ::id int?)
(s/def ::person (s/keys :req [::name]))
(s/def ::item (s/keys :req [::id]))
(extend ::person
Bar
{:bar (fn [this] (::name this))})
(extend ::item
Bar
{:bar (fn [this] (::id this))})
(bar {::name "John Doe"})
(bar {::id 1234})
