Formerly, the accessor for named tuples were more informative:

    >>> class Pt(NamedTuple):
            x: int
            y: int

    >>> vars(Pt)['x']
    <property object at 0x10cc09a70>
    >>> vars(Pt)['x'].fget

Currently, it is less informative:

    >>> vars(Pt)['x']
    <_collections._tuplegetter object at 0x1066a08e0>

The repr should be updated to show how the object could been created:

    >>> vars(Pt)['x']
    _tuplegetter(0, 'Alias for field number 0')
