Episode #14 - January 2022

No Diagnostic Required

In this episode we get a final look at the design of C++23, see how far we can push compile-time computation - and even code generation - in C++20, look at some tools to help us to get there, and what C++ could have been if we weren't burdened with backwards compatiblity.
