Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
A critical opinion piece analyzing the current state and future of C++ modules, arguing that the feature has failed to deliver on its promises of significant compilation speed improvements. The author expresses skepticism about C++ modules' viability, suggesting that unless they can demonstrate 5-10x compilation time speedups on existing open-source projects, the C++ community should reconsider their approach. The piece reflects on the gap between expectations and reality for this long-awaited C++ feature.

Everything that follows is purely my personal opinion as an individual. It should not be seen as any sort of policy of the Meson build system or any other person or organization.
Many people have worked to the best of their abilities on C++ modules, but that does not mean we can't analyze the current situation with a critical eye.
