We hadn't release RC, and we hadn't documented dataclass module yet.
How about making "dataclass" module as porvisional state?

I think we've learned lesson that we shouldn't use typing in modules other than typing...

If it is really needed, I think we should only allow "typing.ClassVar".
All other prefixes seems ambiguous.
