related to - https://github.com/nushell/nushell/pull/9973 - https://github.com/nushell/nushell/pull/9918 thanks to @jntrnr and their super useful tips on this PR, i learned about the parser + evaluation, so 🙏 # Description because we already have `null` as the value of the type `nothing` and as a followup to the two other attempts of mine, i propose to remove the redundant `$nothing` built-in variable 😋 this PR is the first step, deprecating `$nothing`. a followup PR will remove it altogether and wait for 0.87 👍 ⚙️ **details**: a new `NOTHING_VARIABLE_ID = 3` has been added, parsing `$nothing` will create it, finally a `Value::Nothing` will be produced and a warning will be reported. this PR already fixes the `toolkit.nu` module so that it does not throw a bunch of warnings each time 👌 # User-Facing Changes `$nothing` is now deprecated and will be removed in 0.87 ```nushell > $nothing Error: × Deprecated variable ╭─[entry #1:1:1] 1 │ $nothing · ────┬─── · ╰── `$nothing` is deprecated and will be removed in 0.87. ╰──── help: Use `null` instead ``` # Tests + Formatting tests have been updated, especially - `nothing_fails_string` - `nothing_fails_int` which use a variable called `nil` now to make sure `nothing` does not support cell paths 👍 # After Submitting classic deprecation mention 👍 |

Nushell REPL
This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.
Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
