# Description Remove `--numbered` from ~~`for`~~, `each`, `par-each`, `reduce` and `each while`. These all provide indexes (numbering) via the optional second param to their closures. EDIT: Closes #6986. # User-Facing Changes Every command that had `--numbered` listed as "deprecated" in their help docs is affected. # Tests + Formatting Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. --------- Co-authored-by: Darren Schroeder <343840+fdncred@users.noreply.github.com>
