in reply to Method Chaining and Accessors

can't you just test for @_? 
sub foo {
    my $self = shift;  # oops, forgot this line before
    if (@_) {
        $self->{foo} = shift;
        return $self;
    }
    return $self->{foo};
}

    Almost, but because the object arrives in $_[0] either way, you need to shift it out before testing @_, e.g. ...
    sub foo {
    my $self = shift;
    @_ or return $self -> {foo};
    $self ->{foo} = shift;
    $self;
}
