Antoine Pitrou commented on ARROW-10317:
----------------------------------------

One way to do this on the Python side would be to write regular Numpy-formatted 
docstrings for the options classes, then to parse them using {{numpydoc}} so as 
to extract parameter descriptions and inject them into the generated compute 
function docstrings.

We could for example vendor the {{docscrape}} module from {{numpydoc}}: 
https://github.com/numpy/numpydoc/blob/main/numpydoc/docscrape.py

[~jorisvandenbossche] Does it sound reasonable?
