Ahh, I always thought these are undocumented methods, but: "In addition to
the methods inherited from tuples, named tuples support three additional
methods and two attributes. To prevent conflicts with field names, the
method and attribute names start with an underscore."
https://docs.python.org/3/library/collections.html#collections.somenamedtuple._make
I've read somewhere that Raymond Hettinger regrets the naming and now
would favour a trailing underscore to avoid name conflicts.
