It's odd how lazy evaluation is generally seen as a niche design choice, yet the vast majority of languages treat `foo() || bar()` as short-circuiting.

I've had a new Linux laptop for several weeks and only just realised that I didn't have `man` installed! Google is my default the vast majority of the time, and this seems to confirm it.

It took me way too long to realise that Arc<Mutex<T>> is basically a way to create multiple &mut T references (with runtime constraints). This means that you can use plain &T and &mut T in the vast majority of your code. Most code doesn't need to care there's a mutex.
