Description

What it does

Check if something that is re-exported by the crate is used within the crate.

Advantage

The use will show the path to the actual definition and not the re-export.

Drawbacks

(Should be none.)

Example
use crate::Item;

Could be written as:

use crate::collection::Item;

Research direction

The issue names no files, tests, or entry points. Start by clarifying how the proposed check should identify an internal use of a re-export, using the crate::Item and crate::collection::Item examples. Done means the check reliably distinguishes those paths and reports the direct definition path without flagging valid imports.
