Welcome! Embracing Modern C++ Safely is a reference book designed for professionals who develop and maintain large-scale, complex C++ software systems and want to leverage modern C++ features. This book focuses on the productive value of each new language feature, starting with C++11, particularly when the systems and organizations involved are considered at scale. We deliberately left aside ideas and idioms — however clever and intellectually intriguing — that could hurt the bottom line when applied to large-scale systems. Instead, we focus on making wise economic and design decisions, with an understanding of the inevitable trade-offs that arise in any engineering discipline. In doing so, we do our best to steer clear of subjective opinions and recommendations. Richard Feynman famously said, “If it disagrees with experiment, it’s wrong. In that simple statement is the key to science.”1 There is no better way to experiment with a language feature than letting time do its work. We took that to heart and decided to cover only the features of modern C++ that have been part of the Standard for at least five years, which we believe provides enough perspective to properly evaluate the practical impact of new features. Thus, we are able to draw from practical experience to provide a thorough and comprehensive treatment that is worthy of your limited professional development time. If you’re looking for ways to improve your productivity by using tried and true modern C++ features, we hope this book will be the one you’ll reach for. experienced developer, team lead, or manager; that you already have a good command of classic C++98/03; and that you are looking for clear, goaldriven ways to integrate modern C++ features into your toolbox. The goal of the book you’re now reading is to be objective, empirical, and practical. We simply present features, their applicability, and their potential pitfalls as reflected by the analysis of millions of person-hours of using C++11 and C++14 in the development of varied large-scale software systems; personal preference matters have been neutralized to our best ability. We wrote down the distilled truth that remains, which should shape your understanding of what modern C++ has to offer without being skewed by our subjective opinions or domain-specific inclinations. The final analysis and interpretation of what is appropriate for your context is left to you, the reader. This book is, by design, not a C++ style or codingstandards guide; it does, however, provide valuable input to any development organization seeking to author or enhance one. Practicality is important to us in a real-world, economic sense. We examine modern C++ features through the lens of a large company developing and using software in a competitive environment. In addition to showing you how to best utilize a given C++ language feature in practice, our analysis takes into account the costs associated with routinely employing that feature in the ecosystem of a software development organization. Most texts omit the costs of using language features. In other words, we weigh the benefits of successfully using a feature against the hidden cost of its widespread ineffective use (or misuse) and/or the costs associated with training and code review required to reasonably ensure that such ill-conceived use does not occur. We are acutely aware that what applies to one person or a small crew of like-minded individuals is quite different from what works with a large, distributed team. The outcome of this analysis is our signature categorization of features based on how safe they are to adopt — namely, safe, conditionally safe, or unsafe features.
