but if you see `Bar::baz` you can just go to the top of the file, and find the `use something::somewhere::Bar`, and then know what file `Bar` is defined in. In go, the import line only tells you what module/folder it is in, and you either need some tool or some intuition on how the module is organized into files to know what file to look for the definition in.
In Rust, you would see `Bar::baz()` and have no clue where `Bar` is defined. The common style is `use something::somewhere::Bar`.
