That is *exactly* the rationale for disallowing an access declaration which
restricts access to a member.  It wouldn't work.

Hi all,

I have a question about using declarations. In the good old days before
using declarations, there is such a thing called access declarations
that can be used in a derived class to adjust access to base class
names. In ARM, the rule states that access declarations cannot be used
to restrict access to a member that is accessible in the base class.
Does this rule still apply to using declarations? I looked in the
standard and couldn't find the section that discuss it. If this rule no
longer applies, what is the rationale for it, since client code can
always cast the derived class ptr to a base class ptr and access the
member.
