Set::Object::Weak(3)  User Contributed Perl Documentation Set::Object::Weak(3)

NAME
       Set::Object::Weak - Sets	without	the referant reference increment

SYNOPSIS
	use Set::Object::Weak qw(weak_set);

	my $set	= Set::Object::Weak->new( 0, "", {}, [], $object );
	# or
	my $set	= weak_set( 0, "", {}, [], $object );

	print $set->size;  # 2 - the scalars aren't objects

DESCRIPTION
       Sets, but weak.	See "weaken" in	Set::Object.

       Note that the "set" in "Set::Object::Weak" returns weak sets.  This is
       intentional, so that you	can make all the sets in scope weak just by
       changing	"use Set::Object" to "use Set::Object::Weak".

CONSTRUCTORS
       new This	class method is	exactly	the same as "Set::Object->new",	except
	   that	it returns a weak set.

       weak_set( ... )
	   This	optionally exported function is	a shortcut for saying
	   "Set::Object::Weak->new(...)".

       set( ...	)
	   This	method is exported so that if you see:

	    use	Set::Object qw(set);

	   You can turn	it into	using weak sets	lexically with:

	    use	Set::Object::Weak qw(set);

	   Set::Object 1.19 had	a bug in this method that meant	that it	would
	   not add the passed members into it.
