seque silently handles exceptions and returns incorrect results

Question

The seque function silently ends the sequence when an exception is thrown under some circumstances:

`
user> (->> (range 50)

       (map (fn [x] (if (> x 20) (throw (ex-info "hepp" {})) x)))
       (seque 3))

()
`

Instead of returning an empty sequence, I would expect this expression to raise an exception.
