Running cognitect aws-api's pure test namespaces (signing/shapes/protocols/
util/retry/endpoints) surfaced general gaps:
- extend-protocol/extend-type accept a computed class type, e.g.
(Class/forName "[B") for the byte-array class — the byte-array idiom data.json
and aws-api use. The macro grouping handled only symbol/nil heads (it crashed on
a list type); type->name resolves a Class value via .getName; a byte-array
dispatches on the "[B" host tag.
- java.nio.ByteBuffer over a jolt byte-array (wrap/allocate/get/put/array/
remaining/position/limit/duplicate/flip), plus extend-protocol to it.
- java.util.Arrays (equals/copyOf/copyOfRange/fill) and java.util.Random
(nextBytes/nextInt/…).
- java.net.URI/create and clojure.lang.RT/baseLoader statics.
- clojure.core.async/promise-chan (deliver-once, peek-don't-pop).
- a failed java.time parse throws DateTimeParseException (typed), so
(catch DateTimeParseException …) matches it instead of leaking an untyped
condition.
The XML side lives in the jolt-lang/xml library (libxml2 over jolt.ffi); ByteBuffer
stays in core as a generic java.nio primitive.
