AI Analysis

●●●BangerWizardryBig BrainBold Bet

Systems language with custom compiler backend—no LLVM, from lexer to native binary.

Strengths
  • Full compiler pipeline from source to native binary with custom RCU object format and linker
  • Every compilation stage is dumpable for debugging tokens, AST, HIR, LIR, and assembly
  • Version 0.2.2 release shows real progress beyond toy compiler territory
Weaknesses
  • Building a language without LLVM is hard, but the ecosystem and tooling gap is massive
  • No mention of standard library breadth or real-world adoption beyond the core team
Target Audience

Compiler engineers, systems programmers, language design enthusiasts
