Phase 8.2 — Gradual Ownership: - Add tkRef/tkMutRef types and `mut` keyword - Add @[Checked] attribute for opt-in borrow checking - Reject assignment through &T in checked functions - examples/ownership.bux Phase 8.4 — CTFE: - Evaluate const func at compile-time via evalExpr/evalBlock - Fold const declarations to literals; emit #define in C - examples/ctfe.bux (Factorial(10) → 3628800) Phase 8.5 — Trait Bounds: - Change declFuncTypeParams from seq[string] to seq[TypeParam] (name + bound) - Parser handles <T: Comparable> - Sema checks typeImplements at call sites - Fix C backend: generic receivers + pointer self field access - examples/trait_bounds.bux Phase 9.1 — Package Manager: - Inline tables/arrays in TOML parser - bux add, bux install, bux.lock generation - Dependency resolution with git/path sources - Build pipeline merges dependency .bux sources C Backend Fixes: - resolveExprType(ekIdent) now applies typeSubst for generic params - Method desugaring works for monomorphized generic receivers - Pointer checks use isPointer (covers tkRef/tkMutRef) - Field access on &T emits -> instead of . Remove accidentally committed test binaries from tracking
