-* TODO
-** Fixed: Run even if =env()= returns None
-It happens if there is no env-section in .config/nu/config.toml.
-This results in
-#+begin_src rust
-impl Env for Environment {
-    fn env(&self) -> Option<Value> {
-        if let Some(vars) = &self.environment_vars {
-            return Some(vars.clone());
-        }
-
-        None
-    }
-#+end_src
-returning =None=, which completely skips running the code for dealing with directory specific environment variables.
-** Confirm intended behavior
-   - If you are in a directory, or a subdirectory to a directory with a .nu-file, the vars in that .nu-file are applied.
-   - If you leave a directory which set some variables, the variables are unset.
-   - If a directory contains a .nu with an environment variable that was already set, the old value will be overwritten.
-     - This holds even if the old value was set by a .nu in a parent directory. The overwritten value is restored when you leave the directory.
-** Security
-  https://github.com/nushell/nushell/issues/1965
-  - Add trust subcommand
-    - The trust subcommand should hash the current directory path and the content of its .nu-env.
-    - If the directory path changes or the content of the .nu-env changes, show a warning.
-  - Add distrust subcommand
-  - Add command to clear allowed .nu-envs in a directory.
-** Nice errors
-** Potential issues
-    There was previously functionality to track overwritten environment variables, which was used to restore any values that are overwritten.
-    However, it seems that with the current version the already existing nushell functionality takes care of this, in every case I can come up with.
-    Because of that, I just removed the code. It's still there, in the venerable git log if anything ever changes `acd3215b` `Remove overwritten values tracking, as it is not needed`.
-    (I am making a note of this as I half expect someone to come up with a scenario which requires this to be re-added.)
-** mknuenv
-  mknuenv(key=val, key=val)
