Any object that supports the in operator can be passed as the choices value, so dict objects, set objects, custom containers, etc. are all supported. (from http://docs.python.org/dev/library/argparse.html#choices ) Actual behaviour is contradicted by the docs - it seems the container must additionally be iterable. When using a custom container, argparse b0rks on trying to iterate through choices. Using a metavar prevents this, but it still breaks on cases where the element is not in the container.
