Summary

Jason Turner’s talk at NDC Toronto 2026 explores the concept of expression-based programming in C++, arguing that treating statements as expressions can lead to better code. He begins by discussing return value optimization (RVO) and tail call elimination, demonstrating with examples how compilers handle these optimizations. Turner emphasizes that RVO is not dependent on optimization levels and is guaranteed in certain cases, while tail call elimination is toolchain-dependent. He then contrasts expression-based and statement-based code patterns, showing that expression-based approaches often lead to more efficient and cleaner code, especially when combined with RVO. He provides several examples, including string initialization and enum-to-string conversion, illustrating how expression-based code can reduce function size and improve performance. Turner also touches on the importance of function length limits and cyclomatic complexity, suggesting that expression-based programming can help manage these. The talk concludes with practical advice for writing more expression-based C++ code, such as using constexpr functions and avoiding unnecessary assignments. Throughout, Turner engages with the audience, encouraging questions and interaction.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable insights into C++ optimization techniques, particularly RVO and tail call elimination, with clear examples and demonstrations. Turner’s argumentation is solid, based on his extensive experience and practical testing. He effectively shows how expression-based programming can lead to more efficient and maintainable code, though some claims are anecdotal and not backed by formal studies. The interactive format adds value, as audience questions clarify points and provide real-world perspectives.

Scientific Rigor, Source Quality, Title Accuracy

The talk demonstrates scientific rigor through practical examples and compiler behavior analysis. However, sources are limited to the speaker’s own experience and compiler documentation, with no formal citations. The title accurately reflects the content, which is focused on expression-based programming in C++. The talk is well-structured and technically accurate, though some claims are based on personal observation rather than peer-reviewed research.
