Description
I started this in January and haven't written a line of the compiler myself. Coding agents write every line; I do design and taste. Wado is a Rust-flavored, GC'd language for WebAssembly Component Model.Try it in the browser, and ask me anything!

Could you build this?
No Designing and building a functional garbage-collected language targeting the WebAssembly Component Model requires extensive compiler engineering, type theory, and low-level bytecode/runtime generation.
What it would actually take: Requires building a full compiler architecture (lexer, AST, semantic analyzer, monomorphization, GC integration, and code generation) specifically conforming to the complex WebAssembly Component Model / WIT specifications. Even with AI assistance writing code lines, architecting correct memory models, garbage collection runtimes, and ABI component bindings requires expert compiler knowledge.
