Han brings Korean Hangul keywords to Rust-compiled language

Han is a compelling cultural experiment that doubles as a serious compiler engineering exercise — the fact that it ships an LSP server and VS Code extension puts it several rungs above typical "fun language" weekend hacks.

• –Every primitive and keyword maps to Korean: `함수` (function), `만약`/`아니면` (if/else), `시도`/`실패` (try/catch) — making it genuinely readable to Korean speakers without any English mental translation
• –The compiler avoids a hard LLVM dependency by generating LLVM IR as plain text strings and handing off to `clang`, keeping the build a simple `cargo build`
• –An ironic HN finding: Korean Hangul averages 2–3 LLM tokens per keyword vs. 1 for English, so the language is actually *less* efficient for AI-assisted coding due to tokenizer bias
• –Prior art exists (Nuri, Yaksok), but Han's full Rust toolchain and LSP support make it the most developer-tooling-complete Korean language to date
• –The broader trend is real: APL used math symbols, Arabic and Chinese programming languages have been attempted — the question of whether natural language keywords reduce barriers for non-English speakers is worth taking seriously
