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.

If function f1 is unused, and f2 is only called from f1, Rust complains that both f1 and f2 are unused.
I find this confusing: it's useful to know that I can remove both functions, but removing f2 alone gives a compile error.
Not sure what the best tradeoff is though.
It's pretty scary how often Pacman complains about invalidly signed packages -- very likely my binaries used to just get silently corrupted.
