# Description
* Primary purpose is to fix an issue with a missing escaped opening
parenthesis in the warning message when running an old `dirs` alias.
This was creating an error condition from improper interpolation.
Also
* Incorporates #13842 feedback from @kubouch by renaming `std/lib` to
`std/util`
* Removes duplication of code in `export-env`
* Renames submodule exports to `std/<submodule>` rather than
`./<submodule>` - No user-facing change other than `view files` appears
"prettier".
* In #13842, I converted the test cases to use `use std/<module>`
syntax. Previously, the tests were (effectively) using `use std *` (due
to pre-existing bugs, now fixed).
So "before", we only had test coverage on `use std *`, and "after" we
only had test coverage on `use std/<module>`. I've started adding test
cases so that we have coverage on *both* scenarios going forward.
For now, `formats` and `util` have been updated with tests for both
scenarios. I'll continue adding the others in future PRs.
# User-Facing Changes
No user-facing changes - Bug fix, refactor, and test cases only
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
# After Submitting
Still working on updating the Doc. I ran into the `dirs` issue while
writing it and rabbit-trailed to fix it in this PR.
