Unfortunately you can't create a reference to an object method due to the fact that calling an object method is really just dereferencing the object with some blessed magic. One approach would be to use an anonymous sub e.g 
iterate(sub { $rep->attach(@_) }, @param);

But as is suggested in the nodes above, it'll probably be better to refactor your sub.
