MidBig BrainRabbit Hole

MLIR-backed systems language with formal verification, but still pre-1.0 and unproven.

Strengths
  • Z3-powered formal verification baked into compilation pipeline is genuinely novel approach to safety
  • MLIR backbone + syntax borrowed from Julia, Rust, F#, Go shows thoughtful language design
  • Playground in WASM lowers barrier to experimentation without local setup friction
Weaknesses
  • Pre-release language with no production adoption; claim of outperforming Rust is unverified
  • Systems language space is crowded (Rust, Zig, C++); adoption requires ecosystem and libraries
Target Audience

Systems programmers, language enthusiasts, performance-critical workload developers

Post Description

Hey HN,

I wanted to share the new online playground for Salt (https://salt-lang.dev/playground/), a sovereign systems language designed for high-performance, distributed workloads where paying an "abstraction tax" is no longer acceptable.

We started building Salt to bridge the gap between the raw power of manual pointer arithmetic and the safety guarantees of modern high-level languages. The architecture relies on an MLIR-based backbone and a Z3-powered "formal shadow," and the design is rooted in three main pillars:

Fast Enough: The target is to stay within 20% of C's performance, while aiming to consistently outperform Rust.

Supremely Ergonomic: We didn't want to reinvent the wheel on syntax. Instead, we've shamelessly adopted the best features and syntax patterns from Julia, F#, Rust, C, Python, Haskell, Erlang, and Go.

Formally Verified: We've integrated Z3 directly into the compilation pipeline to mathematically prove safety without sacrificing developer velocity.

You can spin up the compiler directly in your browser and mess around with the syntax and verification engine without installing anything locally.

One more link to the project landing page: https://salt-lang.dev, and as always, thanks for reading.
