I want extern "fil-C"

Rust's C FFI enables access to legacy code but requires trusting unsafe C libraries to maintain memory safety. The author proposes creating a Rust FFI that interfaces with Fil-C, a memory-safe reimplementation of C/C++ with runtime checks and garbage collection, which would allow existing C dependencies to remain safe while incentivizing performance-critical code to be rewritten in Rust. The infrastructure for this bridge is partially underway through projects like filnix and Zig's proposed fil ABI, which could shift C from a "fast path" to a "safe compatibility path."
