When are they rewriting Unix `tee` in Rust? It’s only 350 lines of code. 🦀
Seems to me like the easiest way to achieve memory safe tee everywhere. 🙃

It's going to take a bit more time for the collaborative trip report to make r/cpp, so here's an explanation on what happened with C++ profiles, their relevance to safety/security, and why this is a great outcome for quality of the feature and speed of delivery.

C++’s legacy is C. One hard aspect is how file-based its build model is. It tried to change with modules, but arguably isn’t there.
But now, C++ is considering how to fix many issues including security and will introduce an enterprise ready solution:
- pro files
- semipro files
- free tier files
