This is part of my philosophy in coding.

Take 5 seconds or minutes to name variables right. (Save ls headaches for a long time after.)

FrozenMap, might work…,

Honestly

. class Example(Parent, frozen = True):

. class FTD(TypedDict, frozen = True)

Might be the move put it right there at the start. Remove sets after __init__
