Certain sets of names and function signatures are always reserved to the
implementation:
— Each name that contains a double underscore _ _ or begins with an
underscore followed by an uppercase letter (2.12) is reserved to the
implementation for any use.
— Each name that begins with an underscore is reserved to the
implementation for use as a name in the global namespace.
what does "implementation" mean here?
is the following a problem?
class X {
int __x;
int _X;
int _x;
int x_;
}; |

I guess implementation means the compiler, as you see these names in the
libstdc++ headers so yes in the example class it would a problem (at least
in terms of clarity).
