To do that, we need to hook into object construction. Moose lets us do
this by writing a C<BUILD> method in our class. When your class

object construction, but before the object is returned to the caller

Again, as with the C<BUILD> method, we know that the type constraint check has
already happened, so we know that if C<$employees> is defined it will contain
-an array reference of C<Employee> objects..

The B<Person> class does not really demonstrate anything new. It has several
C<required> attributes. It also has a C<predicate> method, which we
