I wonder whether you're talking about object access. Access controls
in C++, however, cover more than that.
You can't programmatically form well-formed dependencies to
inaccessible parts of a class definition, including,
for example, nested types that are private.

That's the whole access of "metadata" vs. "data". C++ access controls
access-control both.
