I was thinking of:

map = Map('myMap')
map.rules[1] = Rule[1]
map.rules[2] = Rule[2]

>>> print map.rules[1]
>>> Map myMap rule number 1
>>> print map.rules[2]
>>> Map myMap rule number 2
>>>
>>> map.mapName = "newname"
>>> print map.rules[1]
>>> Map newname rule number 1
>>> print map.rules[2]
>>> Map newname rule number 2
