Is there any reason *not* to forward declare all forward declarable function parameter/return types?
I ran into a situation where my build speeds have started to become large and have affected productivity. I had already minimized header dependencies before using forward declarations. Now I've turned to forward declarations to further reduce…

Reason for sudden rise in popularity of compile-time annotation processing in Java
So compile-time annotation processing is as old as the annotations themselves in Java. Yet most of the useful libraries were developed with the runtime approach in mind – at least at first.
Now, however, I notice a recent rise in interest in the…

When calculating the runtime of a c++ program, how do you factor in constexpr/tmp functions?
It's mostly all in the title. How do you report the runtime of a C++ program that has intensive calculations at compile-time?
If I have a program that, when I use the bash time command on it, appears to run in .5 seconds, but the COMPILE TIME…

{
Foobar foobar;
#ifndef…

Comparison of build times on various hardware; why non-linear results?
Why do the compile times not vary significantly between different era CPUs, even though disk (NVMe vs. HDD) and CPU benchmarks vary significantly in performance?
Why does disabling hyperthreading affect performance significantly with the Ryzen…

c++ compile-time function check
I am experimenting with complex FSM frameworks. For one of the approaches I am considering I would like to have two types of function: plain function and special function. The exact meaning does not matter. I want to have compile-time enforcement…
