loop-kinds only typed :double accumulators; a ^long-seeded loop var (e.g. (loop [acc start] ...) with a ^long start) stayed generic even though it's sound to fx-type — :long only ever comes from an explicit hint, and a ^long value is already coerced to a fixnum at fn entry. Keep the init's kind (:double or :long) through the fixpoint, demoting only on a recur-arg mismatch. Integer-literal-init loop vars (a bare (loop [i 0] ...)) still stay generic by design: :long is never seeded from a literal, so a bignum-producing loop keeps arbitrary precision. |
