Assigning to repeated field does not work

[skrat]

What version of protobuf and what language are you using? Version: main/v4.25.2 Language: Python

What operating system (Linux, Windows, ...) and version?

Arch Linux

What runtime / compiler are you using (e.g., python version or gcc version)

Python 3.11.6

What did you do?

                    roof = [f for f in doc.faces if f.type == Face.Type.ROOF]
                    # doc.ClearField('faces')
                    # doc.faces.extend(roof)
                    doc.faces[:] = roof

What did you expect to see Success, no errors

What did you see instead?

  File "/home/skrat/Workspace/xxx/rwdom/backend/projects/management/commands/import.py", line 65, in handle
    doc.faces[:] = roof
    ~~~~~~~~~^^^
  File "/home/skrat/Workspace/xxx/rwdom/backend/.venv/lib/python3.11/site-packages/google/protobuf/internal/containers.py", line 348, in __setitem__
    raise TypeError(
TypeError: RepeatedCompositeFieldContainer object does not support item assignment

I know this is said in the lang. guide, but why tho? What's preventing you from making this work? Why can't we assign to repeated message fields?

@anandolee Can you answer why assignment syntax doesn't work for repeated fields?
