print-method/print-dup are now multimethods in the io tier with Clojure's
exact dispatch ((:type meta) keyword, else type — core.clj 3693). On jolt the
dispatch value for a record is its quoted full-name symbol, since class names
aren't values here.
Records used to pr-str as the raw janet table; the renderer's record branch
now prints Clojure's #ns.Type{:k v} syntax, and first consults a callback the
api wires up after the overlay loads — so a user defmethod on a record type
fires everywhere: top level, nested in collections, through pr/prn/pr-str.
Builtin overrides (a :number method) fire only on direct print-method calls;
pr keeps the native fast path (documented divergence).
java.io.Writer arrives as a shim beside the StringReader/StringBuilder ones:
a :jolt/writer tagged value with write/append/flush/toString, a StringWriter
ctor, and a sink variant the renderer callback uses.
Two latent host bugs fixed on the way: the interpreted syntax-quote splice
blew up on ~@nil (an interpreted macro's empty & rest binds nil — first tier
user of defmulti found it; d-realize now treats nil as the empty seq), and
(print-method x nil) now throws like the JVM instead of returning nil.
10 spec rows; bench dead even (sandwich run); greeter green on a fresh
binary.
