More specifically, the original code could be written this way: my $employees = [];
Hopefully that makes it clear that a list enclosed in square brackets is an anonymous list. Assigning that somewhere creates a reference. (That's why you can stuff it in a scalar.)

The original code creates @employees and sets the first (and only) element to a reference to that anonymous list.

    And the push would then be
    push @$employees, $person;
    
    with printing them looking like
    foreach $p (@$employees) {
       print $p->name(),"\n";
    }
    
    Using the array reference would make it easy to stuff this list of employees into another object/list/whatever.
