Error code returns were bad so we invented exceptions. Much better we said.
Then we realised exceptions had their problems - with whole domains outlawing their use altogether. We've been trying to patch them up how we can (with noexcept, for example) - but most of the problems are systemic.

So there's a return to error codes. But now we have new features in the language (arithmetic data types, including variant and optional) - and the promise of more coming (expected, outcome?) - that bring us closer to the best of both worlds, with almost none of the downsides. While the vocabulary types are important, we don't need to wait for them - and the more experience we gain with these approaches the better - especially as std::expected gets locked down, Boost.Outcome goes through final reviews.

But there's more. Where do error_code and error_condition fit in? What's all…

Ever since I worked on my amazing little single-header C/C++ library utest.h, which mimics enough of Google’s googletest framework but in a significantly leaner footprint (and a single header!), I’ve wanted something similar for doing benchmarking. Google has their own benchmarking library Google benchmark, but it fails a couple of key tests that I have for libraries:
It isn’t a single header library. It doesn’t support C benchmarks. It is huge.

In part 1 of this series, explore C/C++ language restrictions, their challenges and pitfalls, and examples demonstrating their benefits in optimized code.

One of the biggest new features of C++20 are concepts. Concepts define requirements on template arguments which are enforced by the compiler. This leads to more readable code which clearly expresses intent. Error messages are improved since violations of the constraints defined by concepts can be detected in the early stages of the template instantiation.
This talked is aimed at people with little or no experience with concepts and will introduce generic programming with concepts (constraining templates, writing your own concepts and overloading functions which are constrained by concepts)
