selfhost-loop / bootstrap determinism (push) Has been cancelled
- feat: generic enum support (parser, lowering, codegen — both selfhost + bootstrap)
- enum Result<T,E> { Ok(T), Err(E) } parsing + monomorphization
- tag constant mangling in monomorphized function bodies
- data field access (l-value + r-value) for generated enum instances
- multiple concrete instances in same file
- HIR walker for enum reference mangling (selfhost + bootstrap)
- feat: stdlib Result<T,E> and Option<T> made truly generic
- breaking: explicit type args required (Result<int, String>)
- fix: 'is' operator — lowering to hBinary tag comparison + C backend fallback
- fix: Type_Eq structural comparison (inner types for pointer/slice/tuple)
- fix: hardcoded limit diagnostics (>8 params/variants/captures now emit errors)
- docs: Iter<T> safety warning for dangling pointer
- docs: IMPROVEMENTS.md — comprehensive plan and changelog
- test: generic_enum example added to EXAMPLES
All tests pass (0 FAIL). Selfhost loop deterministic.

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_0като l-value и r-value) - Множество конкретни инстанции в един файл
Result<T,E>иOption<T>в stdlib
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;
}
