> In cases such as ARROW-13025 it's advantageous to avoid boilerplate when dealing with objects which are basic structs of data members. A simple reflection utility (get/set the value of a data member, print the name of a member to string) would allow writing functionality generically in terms of a tuple of properties, greatly reducing boilerplate.
> See a sketch of one such utility here https://gist.github.com/bkietz/7899f477e86df49f21ab17201c518d74
