We do not have the `dev_*`-style printing facilities yet, but we will.

It is not a hard error, but we recommend following the standard Rust
style (and we enforce it, currently). As Linus said, it is a way to
easily differentiate what is what, instead of using a prefix or
suffix:
  - Types (and similar) are in `CamelCase`.
  - Functions (and similar) are in `snake_case`.
  - Statics/consts are in `SCREAMING_CASE`.

See https://rust-lang.github.io/api-guidelines/naming.html
