RIght, the use case would be "frozendict as a simple alternative to a
full class definition", but even less structured than namedtuple in
that the keys may vary as well. That difference means that frozendict
applies more cleanly to semi-structured data manipulated as
dictionaries (think stuff deserialised from JSON) than namedtuple
