If an in-scope item has the same name as a crate name in the [extern prelude], then `use` of that crate name requires a leading `::` to unambiguously select the crate name or `crate::` to use the item from the crate root.

```rust,compile_fail
use std::fs; // Error, this is ambiguous.

mod std {
pub mod fs {}
}
# fn main() {}
```
