 2. [`parse.rs`](https://github.com/sine-fdn/garble-lang/blob/main/src/parse.rs) parses a [`token::Token`](https://github.com/sine-fdn/garble-lang/blob/main/src/token.rs) sequence into an untyped [`ast::Program`](https://github.com/sine-fdn/garble-lang/blob/main/src/ast.rs).
 3. [`check.rs`](https://github.com/sine-fdn/garble-lang/blob/main/src/check.rs) type-checks an untyped [`ast::Program`](https://github.com/sine-fdn/garble-lang/blob/main/src/ast.rs), returning a typed [`ast::Program`](https://github.com/sine-fdn/garble-lang/blob/main/src/ast.rs).
 4. [`compile.rs`](https://github.com/sine-fdn/garble-lang/blob/main/src/compile.rs) converts a well-typed [`ast::Program`](https://github.com/sine-fdn/garble-lang/blob/main/src/ast.rs) into a [`circuit::Circuit`](https://github.com/sine-fdn/garble-lang/blob/main/src/circuit.rs).
