Sometimes we want to express the state of “nothing meaningful” instead of a value. This is the use case for C++17’s std::optional.
Language and library features
Having written about std::variant and std::visit last week, it’s time to string together some modern C++ features to build a naive basic implementation of overload, a proposed C++ feature.
std::variant is a library addition in C++17 for sum types, and std::visit is one of the ways to process the values in a std::variant.
Two weeks ago, I attended the ACCU Conference in Bristol again, and again it was a blast. ACCUConf is by far the most interesting and enjoyable conference I have attended […]

Contrary to Sunday’s orchestrated April Fool’s posts, raw pointers are not going anywhere. However, there are some things in those posts that are based on reality. I’ll go into a […]
There’s some great news coming from the C++ standards committee: Raw pointers are gone – or rather will be in C++20.
In my last post, I wrote about forward declarations for normal classes. Today, I give you some information about forward-declaring templates and enums.
As promised last week in my post about strange include techniques, I will go into reducing compile time dependencies. Reducing dependencies by shifting them from headers to source files can […]
After having had to clean up some unusual #include techniques, I’ll put together some advice on how not to use #include – and how to use it.
