I agree that that's what it does, but I don't agree that it's
incorrect. "const" applies exactly to what it is applied to.
A "const" pointer is a pointer that may not be changed, which
says nothing about the object it designates. You would point
to a const object with a const pointer by saying:
const ConstType * doubleConstP;
ConstType * constTypeP;
would be a variable pointer to a const object, and so on.
