Wado is not Rust: value semantics (deep copy on assign/pass), variant/enum/flags instead of one enum, an effect system, and no lifetimes/borrow-checker/unsafe/macros. Read this cheatsheet before writing, editing, or reviewing Wado (.wado) source — guessing the syntax from general knowledge will be wrong.

For the detailed specification of a specific feature, read the relevant WEP at docs/wep-*.md.
match expressions & statements.Run Wado performance benchmarks (count-prime, mandelbrot, zlib, json, http-routing, …) and wasm-size reports, then update the benchmark/ and wasm-size/ README files. Use when asked to benchmark Wado, measure performance, or refresh the benchmark/wasm-size results.
Analyze and improve the runtime speed of a Wado program's compiled guest Wasm — profile hot functions, read the generated WIR for allocations and copies, reason about the WasmGC cost model, and A/B-measure a fix. Use for guest-side speed work (serde, parsers, numeric loops, hot stdlib). For host-side native compiler profiling see profiling-wado-compiler; for wrong-code in an optimizer pass see optimizer-debug.
Project rules for opening a PR: a Conventional Commits title, and a description scoped to origin/main...HEAD (three-dot) with no trial-and-error history and no test section. Read before creating or editing any pull request.
Profile the native Rust `wado` binary (compile/serve/run) with a sampling profiler to find host-side bottlenecks. Use for native CPU profiling, not guest wasm (see wado-performance for that).
Transpile Wado Wasm components to JS with jco and run/benchmark them on Node. Use when running Wado on Node or browsers via jco, debugging jco-transpiled runtime failures, or benchmarking Wado on Node.
Mandatory task-completion flow: self-review the branch, update docs (spec/cheatsheet/compiler/optimizer), then run `mise run on-task-done` (build, clippy-fix, golden + format fixtures, doc-stdlib, format, tests; 40+ min) and commit its generated changes. Run before committing a finished task or opening a PR.
