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 👍
