# AILang Roadmap
|
||
|
||
Priority-ordered list of upcoming work — milestones, features, todos,
|
||
and ideas. The orchestrator maintains this file. The user can request
|
||
additions; the orchestrator chooses what to remove or reprioritise as
|
||
work progresses.
|
||
|
||
## Conventions
|
||
|
||
- One checkbox per entry. `- [ ]` is open; `- [~]` is in progress
|
||
(work has started — a plan exists, a branch is open, or commits are
|
||
landing); `- [x]` is done. A finished entry may stay briefly for
|
||
context, then is removed (with a one-line mirror in
|
||
`docs/JOURNAL.md`).
|
||
- Each entry is tagged by **kind** and lives under a **priority**
|
||
bucket:
|
||
- **\[milestone\]** — big chunk that will get a `docs/specs/<milestone>.md`.
|
||
- **\[feature\]** — smaller addition inside a milestone, no full
|
||
spec.
|
||
- **\[todo\]** — concrete task that can run without a brainstorm
|
||
(cleanup, doc fix, mechanical refactor, test backfill).
|
||
- **\[idea\]** — not yet decision-ready, no commitment.
|
||
- Optional `depends on:` line names another entry that has to land
|
||
first.
|
||
- Optional `context:` line points to the JOURNAL entry where the
|
||
rationale lives. The roadmap is intentionally terse; rationale
|
||
stays in JOURNAL.
|
||
- Priority buckets:
|
||
- **P0** — in flight. Spec or plan already exists.
|
||
- **P1** — next up. Decision made; not yet started.
|
||
- **P2** — medium-term. Decided in principle, scheduled later.
|
||
- **P3** — ideas. No commitment; may be cut.
|
||
|
||
## P0 — In flight
|
||
|
||
- [~] **\[milestone\]** design-md-consolidation — `docs/DESIGN.md`
|
||
becomes a state-only specification across four thematic sweeps
|
||
(history anchors out, migration plans out, schema-SoT inversion +
|
||
data-model hardening, workflow / cross-reference cleanup).
|
||
- context: `docs/specs/2026-05-10-design-md-consolidation.md`
|
||
- sub-entries:
|
||
- [x] Sweep 1 — remove history anchors
|
||
- [ ] Sweep 2 — REVERTED + migration plans out
|
||
- [ ] Sweep 3 — schema SoT inversion + data-model hardening
|
||
- [ ] Sweep 4 — workflow / cross-reference cleanup
|
||
|
||
## P1 — Next
|
||
|
||
- [ ] **\[milestone\]** Post-22 Prelude — ship `Show` / `Eq` / `Ord`
|
||
with the four primitive instances (Int, Bool, Str, Float); rewire
|
||
`print` through `Show.show`. Originally queued as 22b.4 in the
|
||
typeclass milestone, kept on hold pending demand.
|
||
- context: JOURNAL 2026-05-09 ("JOURNAL queue")
|
||
- depends on: design-md-consolidation (touches DESIGN.md schema
|
||
sections that the consolidation will reshape)
|
||
|
||
## P2 — Medium-term
|
||
|
||
- [ ] **\[feature\]** Operator routing through `Eq` / `Ord` — `==`,
|
||
`<` etc. resolved via the typeclass instead of the built-in
|
||
primitive comparators. No commitment; gated on bench re-baselining
|
||
to make sure the indirection doesn't tank latency.
|
||
- context: JOURNAL 2026-05-09
|
||
- depends on: Post-22 Prelude
|
||
- [ ] **\[todo\]** `types` / `ctor_index` overlay shape question —
|
||
decide whether the env's two parallel ctor maps should collapse
|
||
into one overlay, or stay split. Surfaced during the
|
||
env-construction unify audit.
|
||
- context: JOURNAL 2026-05-10 ("Audit close: env-construction unify")
|
||
- [ ] **\[feature\]** 22c — typeclass corpus expansion. User-defined
|
||
classes beyond the prelude four; multi-parameter classes; superclass
|
||
chains; richer instance bodies. Deferred from milestone 22.
|
||
- context: JOURNAL 2026-05-09
|
||
- [ ] **\[todo\]** Boehm full retirement — remove the transitional
|
||
Boehm GC path now that RC + uniqueness is the canonical memory
|
||
story.
|
||
- context: JOURNAL pre-22, "Boehm transitional"
|
||
- [ ] **\[feature\]** Closure-pair slab / pool — codegen tweak to
|
||
pool the env+code closure pairs instead of one-shot heap allocs.
|
||
Bench-gated.
|
||
- [ ] **\[todo\]** `FnDef::synthetic` flag — formalise the
|
||
monomorphiser-emitted FnDefs so downstream passes can tell
|
||
user-authored from synthesised at a glance. Currently inferred from
|
||
symbol naming.
|
||
- [ ] **\[todo\]** 21'h iteration — final 21' carry-over (latency
|
||
methodology pass). Numbering kept for continuity with the 21' arc.
|
||
|
||
## P3 — Ideas
|
||
|
||
- [ ] **\[idea\]** Latency methodology rework — switch from per-run
|
||
timing to a histogram-based approach so tail-latency regressions
|
||
are visible without re-running. Queued from 21'g.
|
||
- [ ] **\[idea\]** Parser-test backfill for 22b.4a-era duplicate-clause
|
||
sites (class × 3, class method × 2, instance × 3, instance method
|
||
× 1). No regression pin today; only worth it if a 22b.4a-era
|
||
diagnostic needs to change.
|
||
- context: JOURNAL 2026-05-10 ("Iteration 22-tidy.7")
|
||
- [ ] **\[idea\]** `write_type` `Type::Forall` arm in
|
||
`crates/ailang-prose/src/lib.rs` silently drops constraints in
|
||
inline-type rendering. Dormant — surface forms today only carry
|
||
forall at fn-signature top level. Fix only if a future feature
|
||
carries forall + constraints inline.
|
||
- context: JOURNAL 2026-05-10 ("Iteration 22-tidy.6")
|
||
- [ ] **\[idea\]** Richer integration paths between RC and
|
||
uniqueness — deferred from the 21' arc; revisit once the
|
||
uniqueness inference covers more program shapes.
