**Implementation Steps:** **Implementation Steps:**
1. Parser: extend `for` to accept `for <ident> in <expr> { ... }` 1. ✅ Parser: extend `for` to accept `for <ident> in <expr> { ... }`
2. Desugar to while loop using `Iter_HasNext` / `Iter_Next` or trait-based iterator 2. ✅ Range-based: `for i in lo..hi` and `for i in lo..=hi` — desugared to `while` loop with counter
3. C backend: generate standard while loop with iterator state 3. 🔄 Collection-based: `for x in arr` — needs `Iter<T>` desugaring or trait-based iterator
- Blocked by: generic monomorphization in selfhost C backend
- Once unblocked: desugar to `let __iter = Array_Iter(&arr); while Iter_HasNext(&__iter) { let x = Iter_Next(&__iter); body }`
**Complexity:** Medium — needs either trait system enhancement or hardcoded desugaring. **Complexity:** Medium — range-based done; collection-based needs generic monomorphization first.
