## extern items
When writing extern items (such as `extern "C" fn`), always specify the ABI.
For example, write `extern "C" fn foo ...`, not `extern fn foo ...`, or
`extern "C" { ... }`.
For example, write `extern "C" fn foo ...` or `unsafe extern "C" { ...}`
and avoid `extern fn foo ...` and `unsafe extern { ... }`.
## Imports (`use` statements)
