Let me see... instead of having to capitalize every single usage of a given symbol, I can just prefix it's defintion once with `pub`? Yeap, I rather do that. Instead of replacing all instances to lower case, I can just remove the `pub`. It's obviously better.

Rust is noisy in other parts, for other reasons (trying to explain to compiler how to write super fast and data-race free code). But visibility qualifiers are not a problem.

`extern` is only for importing crates, which is like 10 lines at in whole package/crate. Irrelevant.
