URL to the section(s) of the book with this problem: https://doc.rust-lang.org/book/appendix-02-operators.html

Description of the problem: Outdated explanation of ::path in Appendix B: Table B-3 As of the 2018 edition, starting a path with :: refers to the extern prelude, rather than the crate root. (source: https://doc.rust-lang.org/reference/paths.html#path-qualifiers)

Suggested fix: Change explanation to

Path relative to the extern prelude (i.e., an explicitly absolute path)
