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.

Reviewing some of my earliest web projects: they have a mix of Postgres, MySQL and Mongo. These days I just use sqlite for all my personal projects. It's really good at my scale and makes deploying very easier.

Are there any developer experience advantages for `x := 1` over `let x = 1`? A `let` keyword probably improves parsing error behaviour, and makes declarations more visible. := is more concise though.
