The alias functions now duplicate a lot of near-identical doctest text. For cases like make_list/array and the various list_* or array_* aliases, consider keeping the runnable example on the canonical function and letting alias docstrings point back to it. That would keep this module smaller and make future example edits less repetitive.

There was a problem hiding this comment.
array_agg is an aggregate function rather than a scalar array/list helper, so its new example feels a little outside the stated scope of this PR.

Rationale for this change
Add example usage to docstrings for Scalar array/list functions to improve documentation.
What changes are included in this PR?
The first PR was basically adding a docstring to everything in functions. I broke it apart into a PR (that already merged) for the infra. I then reviewed and merged an example PR of adding the docstrings in parts. This is now the follow up opening a handful of PRs for the remaining functions in functions.py Everything is co-authored with Claude since I used claude to extend the handwritten examples I wrote for reference and to split apart the large PR rather than doing it manually.
I've reviewed all the code prior to PR.
Are there any user-facing changes?
No
