Set::Scalar 1.20

Set::Scalar Perl module contains a basic set of operations.

SYNOPSIS

use Set::Scalar;
$s = Set::Scalar->new;
$s->insert('a', 'b');
$s->delete('b');
$t = Set::Scalar->new('x', 'y', $z);

Creating

$s = Set::Scalar->new;
$s = Set::Scalar->new(@members);

$t = $s->clone;
$t = $s->copy; # clone of clone

Modifying

$s->insert(@members);
$s->delete(@members);
$s->invert(@members); # insert if hasn't, delete if has

$s->clear; # removes all the elements

Note that clear() only releases the memory used by the set to be reused by Perl; it will not reduce the overall memory use.
