ArgumentParser maps dash to underscore in flags, but not positional arguments?

I'm using Python 2.7.3.
It looks like ArgumentParser maps "--foo-bar" to "foo_bar" in the argument namespace, but doesn't do the same kind of mapping for positional arguments. Is this intentional? I can't find in the docs where it describes this mapping, but it's certainly convenient, and seems wrong that it doesn't do it everywhere.
---------------------------------
from argparse import ArgumentParser
parser = ArgumentParser()
parser.add_argument("upload-dir")
parser.add_argument("--file-name")
args = parser.parse_args()
print args
---------------------------------
$ python args.py x
Namespace(file_name=None, upload-dir='x')
