- Introduces a memory-safe compilation mode inspired by Fil-C, which differs from Rust by offering stronger memory safety guarantees without relying on unsafe code or escape hatches.
- Proposes a new ABI named 'fil' to implement Fil-C techniques, including invisicaps and syscall interception, for full memory safety across Zig and C/C++ dependencies.
- Aims to achieve memory safety with a performance penalty of 1-6x, preventing use-after-free and type confusion through unique type IDs and runtime pointer provenance checks.
- Discusses challenges such as intercepting all syscalls and inline assembly, while avoiding language changes by using compiler and standard library modifications.
- Highlights the potential for Zig to become a leading toolchain for memory-safe executables, even with C/C++ dependencies, surpassing Rust's safety in practice.
