Guiding principles:
- Maintain stability and compatibility with C++98 and possibly with C;
- Prefer introduction of new features through the standard library, rather than extending the core language;
- Prefer changes that can evolve programming technique;
- Improve C++ to facilitate systems and library design, rather than to introduce new features only useful to specific applications;
- Increase type safety by providing safer alternatives to current, unsafe techniques;
- Increase performance and the ability to work directly with hardware;
- Provide proper solutions for real world problems;
- Implement “zero-overhead” principle (additional support required by some utilities must be used only if the utility is used)
