Patch LGTM. I think you could create some tests for cases where parsing fails. I also think it is good to put it behind a feature flag, since the error message can make the user think that we already support private members.

I think we're going to forego landing this until the class fields work is close to landing, unless port owners are ok with bleeding edge having that error message (which I suspect is not hit often in practice)
