The convention for named tuple hnas been for all the methods and attributes to be prefixed with an underscore so that the names won't conflict with field names in the named tuple itself. For example, we want to allow Path=namedtuple('Path', ['source', 'destination']). If I had it all to do over again, it might have been better to have had a different convention like source with a trailing underscore, but that ship sailed long ago :-)
