+### String views
+Use `std::string_view` each time you need a string that you will not own, this
+includes: temporary arguments, return values, compile time constants.
+```cpp
+const std::string_view version("1.0");
+auto find(std::string_view id) -> std::optional<int>
+{
+if (auto it = foo.find(id); it != foo.end())
+return it->second;
+return std::nullopt;
+}
+```
