Solo dev ships With v0.15.2, a Rust-safe systems language written with Claude

QuixiAI released With (withlang.org) v0.15.2, an "ergonomics-first" systems language he has been building with Claude since February:
- Pitch: native by default, claimed Rust-level safety, allergic to ceremony—every character the compiler can infer, you never type. No Ok(()), no let =, no trailing returns.
- Safety model: single ownership, consuming destructors, and generational references (inspired by Vale); resources die with their scope, leaking is a defect.
- First-class C: point cimport at a header and call the library directly—no bindings, no CMake, no glue; a migrator ports whole libraries.
- Minimal setup: single binary on macOS/Linux/Windows, no system LLVM needed; the demo goes from empty folder to native window in 28 seconds, with with init plus with get c.raylib bootstrapping a hardware-accelerated graphics app in three commands.
- The author says OpenAI Codex failed at building it; Claude was the only AI that worked.
