I think what Carl meant was if you make a public variable private, the
derived class won't silently use the global variable by the same name.
Meaning there is a compiler error, instead of it "quietly changing the
meaning" of the program to use the global. What I take from that is to
say that getting the compiler error and seeing that you forgot to
change/remove the reference is better than it compiling and accessing a
variable one did not intend.
