A few weeks ago I saw a post about someone converting an entire C++ codebase to Rust using AI in under two weeks.That inspired me — if AI can rewrite a whole language stack that fast, I wanted to try building a programming language from scratch with AI assistance.I've also been noticing growing global interest in Korean language and culture, and I wondered: what would a programming language look like if every keyword was in Hangul (the Korean writing system)?Han is the result. It's a statically-typed language written in Rust with a full compiler pipeline (lexer → parser → AST → interpreter + LLVM IR codegen).It supports arrays, structs with impl blocks, closures, pattern matching, try/catch, file I/O, module imports, a REPL, and a basic LSP server.This is a side project, not a "you should use this instead of Python" pitch. Feedback on language design, compiler architecture, or the Korean keyword choices is very welcome.https://github.com/xodn348/han

Could you build this?
Yes The author explicitly built this Korean programming language interpreter in Rust using AI assistance; modern LLMs excel at writing lexers, parsers, and interpreters.
Discussion
20 comments analyzed.
Competitors mentioned: Python, C, Java, JavaScript
Concerns raised: Creates language fragmentation and reduces collaboration, Programmers already know English-based languages, learning new one adds overhead, Korean syntax order differs from English, making logic harder to reason about, No practical need for non-English programming languages
Feature requests: Live JS compiler for immediate browser execution, Reorder syntax to match Korean writing flow (condition before keyword)
