But then is_asc(-2,-1,0) comes out false.

    0 is false, undef is also false, but 0 is not undef. is_asc(-2,-1,0) returns 0, not undef.
      But if you use it as was suggested (with a ternop ? 1 : 0), then it still evaluates false. If you're going to write a function, at least put the defined test into the function.
