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 hasnt, 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.
