You haven't pretty-printed it to look very nice, but I think all of the
same information (and more due to shrinking) is still in the check-var
output. I don't know of any plan to add what you're asking for beyond
what's below.
{:result
{:clojure.spec/problems
{[]
{*:pred* *(>= (:ret %) (-> % :args :start))*,
*:val* *{:args {:start -1, :end 2}, :ret -2}*,
:via [],
:in []}},
* :failed-on :fn*},
:seed 1466016600676,
:failing-size 4,
:num-tests 5,
:fail [(-1 2)],
:shrunk
{:total-nodes-visited 5,
:depth 1,
:result
{:clojure.spec/problems
{[]
{:pred (>= (:ret %) (-> % :args :start)),
:val {:args {:start -1, :end 1}, :ret -2},
:via [],
:in []}},
:failed-on :fn},
:smallest [(-1 1)]}}
