I don't know what PBP has to say on the matter, as its one of the few Perl books I haven't bought. But... `sub new { my $self = shift; bless \( my $scalar ), ref $self \|\| $self; }` [download] Is better written as `sub new { my $class = shift; bless \( my $scalar ), $class; }` [download] You don't normally get a blessed reference passed into new(). If you're using `my $foo = Object::Foo->new`, or something similar, its the name of the class (Object::Foo in my example) that's passed into new(). So, `my $class = shift;` is more logical.

sub new {
    my $self = shift;
    bless \( my $scalar ), ref $self || $self;
}

sub new {
    my $class = shift;
    bless \( my $scalar ), $class;
}
[download]

my $foo = Object::Foo->new

my $class = shift;
