I haven't had a chance to study your longer posts, but it seems to me that the
AddFruitAction example could just as well be implemented with
parser.add_argument('--color', nargs='*', action='append')
with post parsing processing to create the 'fruits' dicts from the appended
lists.
The basic logic of argparse is to accept optionals in any order, and
positionals in strict positional order. 'nargs' allows us to pair any number
of strings with each optional's flag.
While custom Action classes can implement interactions between arguments based
on values in the namespace, it is usually easier to do this after parsing.
But back to your core change, I wonder if adding a new nargs, such as '**'
would be better than than the new parameter 'greedy_star=True'. I prefer not
to add parameters that are hard to document. At this point in the argparse
development, changes should be minimally invasive.
