Talk Preview - The Surprising Power of Small Wrapper Classes in C++
summary
Small wrapper classes claim to reduce duplication and enable isolated testing by encapsulating single responsibilities so modules can be reviewed and run independently while composition still yields correct results. Examples include concrete wrapper implementations, test harnesses that mock only the wrapper layer, and a comparison showing fewer bugs and faster reviews on several real codebases. Common pitfalls such as over-encapsulation and hidden conversion costs are shown with fixes and performance numbers.
