Could you build this?
No Creating a custom effect runtime and REPL using WebAssembly fibers in Rust requires profound systems programming, runtime design, and compiler knowledge.
What it would actually take: This project requires building a runtime that leverages WebAssembly stack-switching proposals or fiber runtimes (such as Wasmtime with async support or custom stack-switching implementations). It entails implementing an algebraic effect system or cooperative multitasking scheduler in Rust, along with an interactive WASM-aware REPL compiler. This requires specialized expertise in low-level systems programming, WebAssembly internals, and language runtime architecture.
