Just intended to be a dictionary that uses a named tuple type (or other
type with the same named attributes available) as the keys. You initialize
it by telling it what the type is, similar to defaultdict:
dd = defaultdict(list)
...except the type is a NT-like class:
class MyNamedTuple(NamedTuple):
spam: str
eggs: str
nd = NamedKeyDict(MyNamedTuple)
Now if you add a key using named arguments, it will call MyNamedTuple and
supply them as kwargs:
nd[spam="foo", eggs="bar"] = "baz"
...results in:
>>> nd
{MyNamedTuple(spam='foo', eggs='bar'): 'baz'}
