But if numbers should default to positive but not be coerced to
negative, e.g., a -189 just for (shor

I am because the OP was.
ur=> (map #(Integer/parseInt % 16) ["ff43" "0032"])
(65347 50)
...that yields, not shorts.
At the risk of diverging from the question: why are you concerned with
the specific type of the number?
You realize that Java doesn't allocate less memory for a short than
for an int, right? The on

I want to use clojure's short form on them, but short expects an

Any suggestions would be gratefully appreciated!!

authentic hex input, e.g.
(short 0xff43)
it will not accept something like (short "0xff43")
