[New-bugs-announce] [issue33474] Support immutability per-field in dataclasses

[Daniel Lindeman]

New submission from Daniel Lindeman <lindemda at gmail.com>:

Currently, all fields in dataclasses can be frozen by passing frozen=True to the decorator. There are cases where it would be useful to have some fields be mutable, and others immutable. By using a strategy similar to how the decorator frozen works, using __setattr__ and __delattr__, it would be possible to support immutability per-field. This could perhaps be done by adding a frozen argument to the field constructor.
