IMO these should be called __asdict__, __replace__ and

own single-underscore names, so using a single underscore
is not sufficient to prevent name collisions.
namedtuple won't let you use names starting with an underscore, so the
single underscore names are sufficient.
Not for members perhaps, but nothing prevents you from defining methods
with these names in a subclass AFAIK.
Good point. You can define methods or other attributes this way:
>>> from collections import namedtuple
>>> A = namedtuple('A', 'x y')
>>> class B(A):
... _replace = 3
...
>>> b = B(1, 2)
>>> b._replace
3
