I guess this must be the fearless concurrency I am hearing about. /s

In general I understand why people like RAII and the idea of not worrying about pesky details such as resource cleanup is appealing, but the philosophy in C is that the compiler should not do such things behind your back and perhaps this is sometimes valuable. I like this more because things are explicit and visible and I rather want to have tools that tell me that what I do is correct rather than a language that does a lot of things implicitly behind my back (especially if this is correct 99% of times but sometimes surprisingly is not). This is why I am not a fan of C++ nor Rust. Thank you for the nice example illustrating issues in Rust arising from this.
