summary

Argues that assuming pure functions (no side effects) makes code predictable, reproducible and locally reasoned and shows a concrete model of a compiler as a function evolving from compile(string_view) -> vector<byte> into a richer CompilationResult with optional<byte[]> plus diagnostics: vector<string> and a CompilationOptions flag that, when set, returns dependencies: vector<filesystem::path>. Demonstrates optional output for ill-formed input and how signatures document behavior without implementation.
