This seems incorrect. A member-declaration can also introduce typedef names and other things which are non-functions. Your change would mean they are considered data members.

@jwakely I didn't say: "class data members are introduced by a member-declaration". What I said was: class members are introduced by member-declarations. typedef names are not data members but they are class members.

But that's not relevant here. The important point is that you cannot introduce a class data member with a member-declarator. That doesn't make sense. You've got to use a member-declaration to introduce a data member into a class.

@jwakely I take back what I said earlier. You're right, and I was wrong. Class data members have to be introduced into a class with a member-declarator.
