Замечания:

• такой код не компилируется:

  my_array<bool, 10> a;
  a[0] = true;
  a[1] = a[0];
  assert(a[1]);
  

  {lab_13}[2624]$ make

• такой падает:

  my_array<bool, 10> a;
  a.fill(false);
  a[0] = true;
  a[1] = a[0];
  assert(a[1]);
  

• и такой:

  my_array<bool, 10> a;
  a.fill(false);
  (a[1] = a[0]) = true;
  assert(a[1]);
