When I pull the problems from an exception that I receive from spec when running a test, sometimes I see :pred nil? and sometimes I see

:pred #object[clojure.core$nil_QMARK_
This is making it hard to write the test properly. Any thoughts? Or is there a better way to check that a certain test results in a certain set of problems?
