fix: is-operator, try with generic Result, Unwrap exits on panic
Desugar `is` to tag/value equality in bootstrap and selfhost so LIR
no longer drops hIs as false. Resolve monomorphized Result/Option type
names for `?` (_Tag/_Data). Call bux_exit(1) after Unwrap panic messages.
Add is_operator example and document follow-up fixes.

Bux — План за подобрения (post-v1.0.0)

Дата: 2026-07-28
Статус: Всички приоритетни задачи изпълнени


Свършено (3 сесии, 13 файла, +608/-96 реда)

Сесия 1 — Критични бъгове

# Задача Файлове
B.1 Грешки при хардкоднати лимити (>8 param/variant/capture) src/parser.bux
B.2 is оператор — lowering + codegen src/hir_lower.bux, src/c_backend.bux
B.3 Enum type param парсване (enum Result<T,E>) src/parser.bux
B.4 Type_Eq структурно сравнение src/types.bux
B.6 Iter<T> safety документация lib/Iter.bux
B.8 Generic enum lowering (selfhost) src/hir_lower.bux
B.9 Generic enum lowering (Nim bootstrap) bootstrap/ast.nim, bootstrap/parser.nim, bootstrap/hir_lower.nim

Сесия 2 — Tag/type манглинг

# Задача Файлове
B.7 HIR walker за enum reference манглинг (selfhost + bootstrap) src/hir_lower.bux, bootstrap/hir_lower.nim
generic_enum example + test examples/generic_enum.bux, Makefile

Сесия 3 — Data field достъп + Stdlib

# Задача Файлове
B.10a Data field value-read fix (type resolution за generated enums) bootstrap/hir_lower.nim
B.10b Multiple concrete instance fix (type args от enclosing let) bootstrap/hir_lower.nim
B.10c _Data union field type substitution (T→int в value reads) bootstrap/hir_lower.nim
B.11 Result<T,E> и Option<T> генерични lib/Result.bux, lib/Option.bux, examples/map_remove.bux, tests/stdlib_golden/collections/src/Main.bux

Follow-up fixes (post DeepSeek session)

# Бъг Фикс
F.1 is → LIR unhandled hIs / always false Desugar to == / .tag == in bootstrap + selfhost
F.2 ? + Result<T,E>Result_Tag C error Concrete monomorphized typeName + _Tag/_Data mangling
F.3 Unwrap panic continues with garbage bux_exit(1) after panic in Result/Option
F.4 Regression example examples/is_operator.bux

Резултат

  • Всички тестове: 0 FAIL, 0 error
  • Selfhost loop: детерминистичен (C + ELF identical)
  • Generic enum-ите работят end-to-end:
    • Парсване с type параметри
    • Tag проверки (p.tag == Pair_First)
    • Data field достъп (p.data.First_0 като l-value и r-value)
    • Множество конкретни инстанции в един файл
    • Result<T,E> и Option<T> в stdlib
    • is operator (simple + algebraic enums)
    • ? try operator with monomorphized Result<T,E>

Пример който работи

enum Pair<T, U> {
    First(T), Second(U),
}

func Main() -> int {
    let p: Pair<int, String> = Pair_MakeFirst<int, String>(42);
    if p.tag == Pair_First {
        PrintInt(p.data.First_0 as int64);  // → 42
    }
    let s: Pair<String, int> = Pair_MakeSecond<String, int>(99);
    if s.tag == Pair_Second {
        PrintInt(s.data.Second_0 as int64); // → 99
    }
    return 0;
}
