Could you build this?

Partial The CLI, package manager, docs, and playground are vibe-codeable, but a real statically-typed AOT compiler with LLVM codegen, a type checker, a runtime, and a stdlib needs serious compiler expertise to be correct.

What it would actually take: Write a front end (lexer, parser, type checker with sum types and error-flow analysis), lower to an IR, and generate native code through LLVM, with a runtime and stdlib on top. The hard parts are type-system soundness, correct codegen and memory/runtime semantics, and sustaining an ecosystem (registry, lockfiles, Jupyter kernel), which requires experienced language and compiler engineers.
