[mp2] Method Handlers creating a new object vs ref

[Tim Esselens]

Hi,

>From the practical mod_perl book (focuses on mp 1.x though):

sub new {
        bless {}, shift;
}

#mp1.x uses sub handler($$) {}
sub handler : method { 
        my ($self,$r) = @_;
        $self = $self->new unless ref $self;
        $self->{r} = $r;
}

When exactly is this ref used? AFAIK $_[0] will never be a reference.

kind regards,
Tim Esselens
