Remove autoprinting of loop block values (#8618) # Description This removes autoprinting the final value of a loop, much in the same spirit as not autoprinting values at the end of statements. As we fix these corner cases, it becomes more consistent that to print to the screen in a script, you use the `print` command. This gives a noticeable performance improvement as a bonus. Before: ``` C:\Source\nushell〉 for x in 1..10 { $x } 1 2 3 4 5 6 7 8 9 10 ``` Now: ``` C:\Source\nushell〉 for x in 1..10 { $x } C:\Source\nushell〉 ``` # User-Facing Changes **BREAKING CHANGE** Loops like `for`, `loop`, and `while` will no longer automatically print loop values to the screen. # 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 > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` # 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.

Change `echo` to print when not redirected (#10338) # Description This changes `echo` to work more closely to what users of other shells would expect: * when redirected, `echo` works as before and sends values through the pipeline * when not redirected, `echo` will print values to the screen/terminal # User-Facing Changes A standalone `echo` now will print to the terminal, if not redirected.

Previously result of every but last pipeline in a block was printed to stdout, and last one was returned ![image](https://user-images.githubusercontent.com/17511668/222550110-3f62fbed-432c-4b46-b9b1-4cb45a1f893e.png) With this change results of intermediate pipelines are discarded after they finish and the last one is returned as before: ![image](https://user-images.githubusercontent.com/17511668/222550346-f1e74f80-f6b6-4aa3-98d6-888ea4cb4915.png) Now one should use `print` explicitly to print something to stdout ![image](https://user-images.githubusercontent.com/17511668/222923955-fda0d77b-41b4-4f91-a80f-12b0a1880c05.png) **Note, that this behavior is not limited to functions!** The scope of this change are all blocks.
