OVERLOADED OPERATORS

      # "$index" is a number or a Perl scalar variable containing a
      # number which represents the set containing only that element:

  Emptyness
      if ($set) # if not empty
      if (! $set) # if empty
      unless ($set) # if empty

  Equality
      if ($set1 == $set2)
      if ($set1 != $set2)
      if ($set == $index)
      if ($set != $index)

  Lexical Comparison
      $cmp = $set1 cmp $set2;
      if ($set1 lt $set2)
      if ($set1 le $set2)
      if ($set1 gt $set2)
      if ($set1 ge $set2)
      if ($set1 eq $set2)
      if ($set1 ne $set2)
      $cmp = $set cmp $index;
      if ($set lt $index)
      if ($set le $index)
      if ($set gt $index)
      if ($set ge $index)
      if ($set eq $index)
      if ($set ne $index)

  String Conversion
      $string = "$set";
      print "\$set = '$set'\n";

  Union
      $set1 = $set2 + $set3;
      $set1 += $set2;
      $set1 = $set2 | $set3;
      $set1 |= $set2;
      $set1 = $set2 + $index;
      $set += $index;
      $set1 = $set2 | $index;
      $set |= $index;

  Intersection
      $set1 = $set2 * $set3;
      $set1 *= $set2;
      $set1 = $set2 & $set3;
      $set1 &= $set2;
      $set1 = $set2 * $index;
      $set *= $index;
      $set1 = $set2 & $index;
      $set &= $index;

  Difference
      $set1 = $set2 - $set3;
      $set1 -= $set2;
      $set1 = $set2 - $set1;
      $set1 = $set2 - $index;
      $set1 = $index - $set2;
      $set -= $index;

  ExclusiveOr
      $set1 = $set2 ^ $set3;
      $set1 ^= $set2;
      $set1 = $set2 ^ $index;
      $set ^= $index;

  Complement
      $set1 = -$set2;
      $set1 = ~$set2;
      $set = -$set;
      $set = ~$set;

  Subset Relationship
      if ($set1 <= $set2)

  True Subset Relationship
      if ($set1 < $set2)

  Superset Relationship
      if ($set1 >= $set2)

  True Superset Relationship
      if ($set1 > $set2)

  Norm
      $norm = abs($set);

DESCRIPTION ^

This class lets you dynamically create sets of arbitrary intervals of integers and perform all the basic operations for sets on them (for a list of available methods and operators, see above).

See Bit::Vector(3) for more details!
