SYNOPSYS
  use Comparator::Short;

  my $comparator : Comparator::Short = method : int ($a : short, $b : short); {
    return $a <=> $b;
  };

  my $result = $comparator->(3, 5);

DESCRIPTION
Comparator::Short is a callback interface to compare two short values.

CALLBACK METHOD INTERFACE
  method : int ($a : short, $b : short);

This method must receive two numbers and return 1 if $a is more than $b, -1 if $x is less than $b, 0 if $a equals $b in the implementation.
