I'm attempting to define a method that will calculate the length of an array stored within an object, but am running up against an issue. In the example given below, when I call scaler on the deferenced array (which I would hope would return the array length?), the call behaves as if I'd attempted to call a method of the class called "scaler"? Clearly I'm misunderstanding something fundamental here and would really appreciate any clarification... 
{
    package Test;
    our $AUTOLOAD;

    sub new {
        my ($class) = @_;
        return bless {arr => [1,2,3,4]}, $class;
    }
    
    sub len {
        my ($self) = @_;
        scaler(@{$self->arr});
     }
    
    sub DESTROY {}
    
    sub AUTOLOAD {
        my ($self) = @_;
        (my $f = $AUTOLOAD) =~ s/.+://;
        print "function \"$f\" called\n";
        $self->{$f};
    }
}

my $tmp = Test->new;
print $tmp->len,"\n";
