C++ class scopes have the with problem.

   class foo {
     // int x;
     int y;
     int bar();
   };

   // in another file

   int x;

   foo::bar()  // "with whole friggin class scope ..."
   {
     return x + y;  // global ::x plus class member y
   }

Now uncomment the x in the class declaration, and the x + y now adds two class members.
