MJD shows an implementation of linked lists in Higher Order Perl which looks quite convincing (though costly)

Each node is a two element array [value,tail_ref] with tail_ref being an array ref to the next node or undef.

To count length iterate through the list till you get undef.

Perl has no built in linked lists b/c arrays cover almost all use cases.
