NAME

       Set::Scalar::Valued - valued sets

SYNOPSIS

           use Set::Scalar::Valued;
           $s = Set::Scalar::Valued->new;
           $s->insert(a => 12, 'b c' => $d);
           $s->delete('b c' => $d);
           $t = Set::Scalar->new(x => $y, y => $z);

DESCRIPTION

       Valued sets are an extension of the traditional set concept.  In addition to a member just
       existing in the set, the member also has a distinct value.  You can think of this a
       combination of a traditional set and a Perl hash.

       The used methods are as for the traditional of Set::Scalar, with the difference that when
       creating (new()) or modifying (insert(), delete(), invert()), you must supply twice the
       number of arguments: the member-value pairs, instead of just the members.  Note, though,
       that in the current implementation of delete() the value half is unused, the deletion is
       by the member.  In future implementation this behavior may change so that also the value
       matters.

       There are a couple of additional methods:

           %ve = $s->valued_members;

       which returns the member-value pairs, and

           @v  = $s->values;

       which returns just the values (in the same order as the members() method would return the
       members), and

           $v  = $s->value($member);

       which returns the value of the member.

       The display format of a valued set is the member-value pairs separated by " => ", the
       pairs separated by ", " and enclosed in curly brackets {}.
