PEP 726: Module __setattr__ and __delattr__

[oscarbenjamin]

@sirosen

Pure curiosity here, but has there ever been discussion of making sys.modules use a custom type rather than a list?

It may have been argued in the past that there was no point because it could be replaced by a user at runtime

This PEP does not in itself prevent anyone from replacing an object if they really want to. A determined monkeypatcher can still use sys.__dict__['modules'] = whatever. The intention here is more to prevent accidentally setting attributes. Otherwise the consenting adults principle still applies.
