When talking about a match or a switch statement, I've typically seen people talk about individual 'cases' or 'arms'. TIL Zig uses 'prongs' instead!

Today I learnt about clippy::clone_on_ref_ptr, which complains about t.clone() on a Rc<Thing>. You write Rc::clone(t) instead, so it's obvious it's a cheap clone. It's a nice approach, because it makes the expensive clones more obvious.

Go has an os.Root API that allows you to enforce all paths are subdirectories of a given root. It fixes users accessing foo/../../../etc/passwd and similar. Seems like a really nice solution for a relatively common problem.
