what I'm doing now is 

sub foo {
    my $self = shift;
    $self->query->param('id');
    if (!$id) {return $self->get_id();}
#get_id returns a web page that prompts the user for an id
#this is all running in mod_perl, with CGI::Application
    my $obj = $self->get_obj($id);
    #else do foo kinda stuff with $obj
}

But since I have many foo like sub's I'd like to do something like...

sub foo {
    my $self = shift;
    my $obj = $self->init;
    #do foo kinda stuff with $obj
}
sub init {
    my $self = shift;
    $self->query->param('id');
    if (!$id) {return $self->get_id();}
    my $obj = $self->get_obj($id);
    return($obj);
}

Which wont work because init might return an object to foo (as $obj) or HTML to my C::A (as the output of get_id). I could check the return value of init and act accordingly but I'd rather not. So the question is how do I get the return $self->get_id() in init to return to C::A and not just bounce back to foo?
