Yes, and its exactly equivelent to 

return $self->[ARRAY][$index];

What is the point of the if in your code? If the values of $self->[ARRAY][$index] is defined then we return the value. If its not then we return undef. Whats the point? The value of $self->[ARRAY][$index] should simply be returned. There is no difference. (Except the one is more efficient and less confusing.)

Consider this using different values: 

sub foo {
  my $x=shift;
  if ($x=10) {
     return 10;
  } else {
     return $x;
  }
}

Which is just plain silly isn't it?
