# Iteration 5 — language surface (Haxe-parity adoptions)
|
|
|
|
> Format: fiberloom `product/story-iteration-template`. Part of

|
|
> developer directive overriding the post-12 park) — **`pub(read)` write
|
|

|
|
> **`using` static extensions** (compile-time rewrite to a free-fn call,
|
|

|
|

|
|
> `is`/`throw` stay cut (0 workload uses); `abstract` is a reject row.

## Goals
|
|
|
|
- The language grows from milestone grammar to a daily-driver surface: the
|
|
systems-track verdict table's every **adopt** row — switch expressions,
|
|
typedef records with `?fields`, `?T` optionals with null-narrowing,
|
|
enum payload variants, try/catch/throw over traps, `static` members,
|
|
`abstract` newtypes, `using` extensions, `use` modules, `is`, `pub` /
|
|
`pub(read)`, `#if` build flags, string interpolation, loop control.
|
|
- Every **reject** row (inheritance, `Dynamic`, `cast`, macros, FFI…)
|
|
refuses with a diagnostic citing doctrine — the language's boundaries are
|
|
as deliberate as its features.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- What to achieve?
|
|
- **Given** the verdict table in the systems-track spec,
|
|
- **when** the corpus runs,
|
|
- **then** every adopt row has at least one golden fixture and one
|
|
must-fail fixture passing, and every reject row that would parse
|
|
produces its doctrine-citing diagnostic.
|
|
- What to achieve?
|
|
- **Given** a switch over a union missing one variant and lacking
|
|
`default`,
|
|
- **when** it compiles,
|
|
- **then** the diagnostic names exactly the missing variants.
|
|
- What to achieve?
|
|
- **Given** the three fenced VM changes (catch frames, variant objects,
|
|
boxed scalar optionals),
|
|
- **when** they land,
|
|
- **then** the format doc is updated in the same change and all prior
|
|
trap fixtures still pass byte-for-byte.
|
|
|
|
## Out Of Scope
|
|
|
|
- Stdlib modules and program mode (iteration 6).
|
|
- Any new VM capability beyond the three fenced changes.
|
|
|
|
## Info
|
|
|
|
- Normative table: `docs/superpowers/specs/2026-08-01-systems-track-design.md` Part 1.
|
|
- Order inside the plan matters: modules first (everything imports through
|
|
them), data shapes before optionals, rejects last.
|
|
|
|
## Proposed Solution
|
|
|
|
- Execute the existing plan: `compiler/plan/2026-08-01-haxe-parity-language.md`
|
|
(nine tasks, each shipping its fixtures and error-catalog entries in the
|
|
same task).
