i see onyx is mostly using clojure 1.8, but the onyx-specs repo uses pos-int?, which is a 1.9 function

i assume it's safe to run onyx under 1.9 ?

@lmergen It is, yes. We were waiting for Spec to get out of alpha, but it doesn't look like that's happening any time soon. Might as well move everything to 1.9, there should be no other changes than a dep bump.

right, makes sense
