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.
