  67         According to ECMA 9.3, when input type was Object, should call
  68         ToPrimitive(input arg, hint Number) first, and than ToNumber() later. However,
  69         ToPrimitive() will use [[DefaultValue]](hint) rule when input Type was Object
  70         (ECMA 8.6.2.6). So the input [1,2,3] will applied [[DefaultValue]](hint) rule
  71         with hint Number, and it looks like this:
  72
  73         toString(valuOf([1,2,3]))  => toString(1,2,3) => '1,2,3'
  74
  75         Than ToNumber('1,2,3') results NaN based on ECMA 9.3.1: If the grammar cannot
  76         interpret the string as an expansion of StringNumericLiteral, then the result
  77         of ToNumber is NaN.
