Forget about those two lines for a moment. Why would your comparator return $a, or $b, or -1, 0, 1? The first and final returns will return the result of N <=> M, whereas all the other returns return the value being compared instead. That's got to be a bug.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
