Overload: Build a Variant Visitor on the Fly
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.

Modern C++ Features – std::variant and std::visit
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.
Raw Pointers Are Gonna Stay!
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 […]
Raw Pointers Are Gone!
There’s some great news coming from the C++ standards committee: Raw pointers are gone – or rather will be in C++20.
Modern C++ Features – Class Template Argument Deduction
With C++17, we get class template argument deduction. It is based on template argument deduction for function templates and allows us to get rid of the need for clumsy make_XXX […]
Final Classes
A few days ago, a colleague asked me if it was wise to make every class a final class. Here is a more sophisticated answer than I could give at […]
Constexpr Additions in C++17
Last year, I have written about constexpr and compile time constants in general. Last week, the Draft International Standard for C++17 has been sent to its ballot. Time to provide […]
Implementing Array Access for Tuple
This week I exchange guest posts with Jonathan Müller about accessing tuple elements. Jonathan is a CS student passionate about C++. He’s working on various C++ projects like memory, an […]
Lambda Overdose
Lambdas are a nice recent addition to C++. They are cool, they are hip, and they tend to be overused and misused.
Modern C++ Features – decltype and std::declval
decltype and std::declval are two features that go hand in hand and are most useful in template metaprogramming and in conjunction with the use of type deduction via auto, e.g. […]
