One nice feature of cargo that I wasn't previously aware of: you don't need to do anything after updating your Cargo.toml. In npm, you need to remember to `npm i` after changing package.json. It's not declarative and the state can get out of sync.

One neat way of thinking of assertions vs unit tests: declarative vs imperative:

Most macros I write are `def-foo' (declarative) or `with-foo' (setup then tidying). This gives predictable semantics: important with macros.
