Succint way to create dynamic branches from a named list while ensuring provenance?

Description

Hi - I often find myself creating dynamic branches (sometime writing to a file) from a named list, which, to ensure provenance, often ends up looking something like this:

....
tar_target(some_named_list,  
                  get_named_list()),
tar_target(list_names, 
                  names(some_named_list)),
tar_file(written_file,
             write_file(input=some_named_list, output_file_suffix =list_names,) 
              pattern=map(some_named_list, list_names))
....

which feels quite verbose and clunky. I've also tried using tibbles instead, and saving the names there as a separate column, but it usually ends up being quite clunky as well, having to extract the column values and so on. Has anyone else landed on a good, general approach here?

I've found tibbles are nice if you pattern = map() over the rows.

All right - I'll try to give it another go with tibbles and see if I can get it to work in a less clunky way.
