True.

True.

False. x.__getattr__ can do the case normalization. If you start messing
with the underlying dictionaries you don't get the special behavior.
Objects already do "funny things" in the "." syntax that you don't get
when you go directly to the dictionary.

Also not true. How do you get from "setattr might do case-insensitive
setting" to "A"=="a" everywhere.
