If I have this right, on the discussion about frozen and hash, a use
case was brought up for taking a few steps to create an instance (and
thus wanting it not frozen) and then wanting it hashable.
Which pointed to the idea of a “ freeze this from now on” method.
The problem with a "freeze" method is that it doesn't play well
with subclasses. The object ends up frozen by the base class's
__new__ or __init__, preventing the subclass from doing its own
initialisation unless it uses some form of back-door access.
And if there is a back door, it might as well be used for all
initialisation, maing the freeze method unnecessary.
