in reply to On References to the Unnamed

Wouldn't it be much easier to just introduce a perlvar that each time it's used, is a new scalar? I suggest $^N, New scalar. 

bless \$^N, $class;
bless \($^N = "some value"), $class;

I don't really see why this is needed, though. I can live with 
bless \my $dummy, $class;

or, if for some strange reason I don't want to pollute the lexical scope with a $dummy, 
bless \do { my $dummy }, $class;

    No need for $dummy: 
    sub new {
    my $class = shift;
    bless \$class, $class;
}

    $^N is already taken.
