title: Pass by name and pass by value-result languages
body: <p>For my programming languages course, I'm trying to write some code snippets in languages that use pass by name or pass by value-result, preferably by default, but any language that even supports either of those would be fine. However, I haven't been able to find a single language that supports either of them. Does anyone know of a language that uses pass by value-result or pass by name? Preferably an imperative language.</p>
