Could you build this?

No Designing and building a new Python-like programming language in Rust with a custom runtime and compiler to optimize ML orchestration overhead requires deep compiler design and systems engineering expertise.

What it would actually take: Creating a domain-specific systems language involves building a full compiler frontend (lexer, parser, AST), type system or dynamic type engine, and an interpreter or bytecode VM / LLVM backend in Rust. It also requires tight FFI interoperability with Python C-extensions (NumPy, PyTorch) and distributed asynchronous task scheduling. Achieving lower runtime overhead than existing Python orchestration frameworks demands deep systems architecture and runtime optimization skills.
