AI Analysis

●●SolidBig BrainBold Bet

Safety-first language with explicit Stop-The-World GC and no inheritance — ambitious constraints.

Strengths
  • •Explicit GC triggering gives developers auditable control over runtime costs
  • •No null, no exceptions, no inheritance — forces disciplined error handling patterns
  • •Exhaustive match on union types prevents unhandled cases at compile time
Weaknesses
  • •Compiler written in TypeScript — not yet self-hosted, limits credibility
  • •Safety-first niche already dominated by Rust, Zig, and other established languages
Target Audience

Systems programmers, language designers, safety-critical software developers

Post Description

Hi HN,

I have been working on a new programming language and compiler.

Website: https://ironwall-lang.dev

GitHub: https://github.com/3WyUFvDOdCbBw7gOZHwcfgKF/ironwall

Why a new language is still needed: https://ironwall-lang.dev/en/motivation

The compiler is written in TypeScript at the moment, and work on a self-hosting compiler written in Ironwall is ongoing.

I would be interested in feedback.

Thank you.
