jolt.host/tagged-table, ref-put!, ref-get resolved to jolt-nil on the
prelude, so the 25-sorted tier and every overlay fn that calls sorted?
(empty, ifn?, reversible?, map?, set?, coll?) hit apply-jolt-nil.
host-table.ss provides the three primitives over a Chez mutable htable
record and set!-extends the collection dispatchers (seq/count/get/
contains?/assoc1/dissoc/conj1/disj/empty?/keys/vals/coll?/map?/set? +
printers + equality + value-host-tags) with a sorted arm routing through
each value's :ops table — the seed dispatch pattern, same as records.ss.
first/rest/next fall out free since they seq first. Sorted colls print
in sorted order ({k v, k v} for maps) and = canonicalize like their
unordered counterparts.
emit.janet: a computed call operator (an :invoke/:if expr that yields an
IFn, e.g. ((sorted-map :a 1) :k)) now routes through jolt-invoke instead
of a raw Scheme application.
