- phm.janet: LazySeq (realize-once with caching, ls-first/ls-rest/ls-seq/ls-count)
PersistentHashSet (backed by PHM, phs-conj/phs-disj/phs-contains?/phs-count/...)
make-lazy-seq creates lazy thunk wrapper with :jolt/lazy-seq type tag
make-phs creates hash set with :jolt/set type tag
- evaluator.janet: :jolt/set handler in eval-form, disj/set? special forms,
special-symbol? entries, phm import for compile-time visibility
- core.janet: lazy-seq/iterate macros, set?/disj core fns, make-phs wired
into hash-set, core-bindings entries for set?/disj/lazy-seq/make-lazy-seq/iterate
Set support in core-conj/core-contains?/core-count/core-empty?/core-seq/core-get
LazySeq support in core-first/core-rest/core-count/core-seq
- 9 tests (32-33): lazy-seq basic ops, realize-once caching
PersistentHashSet construction, conj, disj, count, set? predicate
- 315 ok, 2 fail (pre-existing, unchanged)
