naked blocks can be useful in C, because they allow you to declare variables somewhere in a function other than at the start, for example -

void MyFunction()
{
  int a = 10;
  
  printf ("%d",a);
  
  {
    int b = 5;
  
    printf ("%d",b);
  }
}

The following would be illegal in C -

void MyFunction()
{
  int a = 10;
  
  printf ("%d",a);
  
  int b = 5;
  
  printf ("%d",b);
  
}
