Another year, another trip report from C++ On Sea! First, a heartfelt thank-you to the organizers for inviting me to speak, and an equally big thank-you to my wife for taking care of the kids whil...

I wrote a couple of times about dynamic_cast and I discouraged you from using it. In general, it makes code worse in terms of readability. When you get rid of dynamic_cast, either via self-discipli...

Let’s talk about class templates and variadic parameters. How to use them in combination? But first of all, what are variadic templates? Variadic template don’t accept a fixed size of parameters,...

In short, thanks to P2748R5 by Brian Bi, it’s no longer possible to return a reference that binds to a temporary expression, and that’s just lovely. What exactly is changing? Often, a proposal mo...

Let’s talk about getting into conferences. I’ve already shared my path into conference speaking, and more recently, Andre Schau Knatten wrote about how to become a conference speaker. As the ques...

Let’s get back to some basics this week and talk about name lookups in C++. In other words: when you refer to a symbol in your code, how does the compiler find it? Essentially, we can differentiat...

I’ve written plenty on this blog about standard algorithms, but far less about ranges. That’s mostly because, although I’ve had production-ready compilers with C++20 ranges since late 2021, the ori...

Recently, I ran into some code where a class declared itself as a friend. I was quite surprised to see that and at a second glance, I realised that there were 2 characters difference in a relativel...

In recent weeks, we’ve explored language features and library features becoming constexpr in C++26. Those articles weren’t exhaustive — I deliberately left out one major topic: exceptions. Startin...

Last week, we discussed language features that are becoming constexpr in C++26. Today, let’s turn our attention to the standard library features that will soon be usable at compile time. One topic ...
