You could also not make anything private and put a comment over
members, saying "please do not modify these."

If you can backdoor a language feature so simply and so trivially...
what is the point of it at all? I mean, it's bad enough that any
serious reflection feature will make it possible to reflect past
access classes. But at least reflection is hard to write. We shouldn't
add a language feature to break private access with a single keyword.
