int sizeof(int a) { return 42; }
int nameof(int a) { return 99; }

int a;
int x = sizeof(a)    //42
int y = a.sizeof()   //Error: function expected before () ...
int z = a.sizeof     //4, but dangerous, maybe the user expects 42

int xx = nameof(a)    //99
int yy = a.nameof()   //Error: function expected before () ...
int zz = a.nameof     //Error: cannot implicitly ... string to int
