True, that does help when you want to dig into things. I think my main pain-point here is that without extra tooling, the reference is not surfaced. Compare this to Clojure, where every reference is explicit, things normally don't get "magically" created in your scope. Just by searching for a var in the current file upwards (up to the `ns` declaration), you can find out where code is coming from, which is not always possible in Rust.
