Python cryptography, Rust, and Gentoo

All of those are lists of why what appears to be simple in C++ ("just" create a std::mutex at global scope) are in fact not simple at all once you consider the details. It's just that C++'s (and C's) way of doing things relies on you knowing that it's not that simple, and that you have a whole boatload of other complexity to consider when doing this.

And Rust globals are writable - you have to use the unsafe marker with writes to a global, because writing to a global without sufficient consideration of concurrency results in memory unsafety (in C, Rust, or C++ - this is a common thing to all systems languages). C++ just doesn't force you to confront that front-and-centre, where Rust does.
