No Advent of Code for me. Instead, I've used the break to write the type-erasure library I have always wanted.

C++ doesn't make it easy to have both dynamic polymorphism *and* value semantics, but this little utility does!

Interfaces can extend other interfaces, and it works in consteval, too. 🤩
a screenshot of an editor showing a snippet of code that defines an interface, and a type that models the interface non-intrusively, and a type named `any` that is parameterized on the interface and that stores the model while erasing its type.

FYI, besides having the evolution of C++11->C++26 and an adventure game, my website now also has a fully cross-linked database of C++ Weekly episodes!

Want to see which episodes correlate to which parts of the standard and then jump into the adventure game engine to explore?

I've built a text adventure game engine on top of the C++ Standard. Why? I have no idea. But it's a learning tool with quests and time travel and artifacts and NPC's and XP and ... well, you just have to check it out!

This December, I'll be posting an article & video each day until Christmas in the Advent of Compiler Optimisations! #AoCO2025
Each day we'll explore a fun optimisation in C or C++; some low-level, x86 or ARM-specific, some high-level. Hope you'll join me!
