Document how to get valid enum labels from client side
Yesterday I played around with the pyhtonic ways to use enum attributes, see https://pytango.readthedocs.io/en/stable/data_types.html#devenum-pythonic-usage.
And other quite some trial and error I found out that you can get a list of valid enum member names from the client side from the attribute _member_names_
of the instance of the enum attribute (noon
in the linked example). Is that documented somewhere?
Or do we want to teach tango.utils.get_enum_labels
to return _member_names_
from enum instances?
