algo.monads: a seq reports IPersistentList for protocol dispatch
algo.monads' writer monad extends a protocol to clojure.lang.IPersistentList,
but jolt's lists only reported ASeq/ISeq in value-host-tags, so writer-m-add
didn't dispatch ("No method writer-m-add"). jolt models every seq as a list (no
distinct LazySeq — (class (map inc xs)) is PersistentList), so a seq now also
reports PersistentList / IPersistentList / IPersistentStack, in value-host-tags
and host-type-set. extend-protocol clojure.lang.IPersistentList then dispatches
on a list.
algo.monads passes its whole suite (11/11) over tools.macro. Listed in docs +
site. Runtime only, no re-mint. make test green (+1 corpus row, 0 new
divergences), shakesmoke byte-identical.
