=head2 Object Representation
By far the most common mechanism used in Perl to represent a Pascal
-record, a C struct, or a C++ class an anonymous hash. That's because a
+record, a C struct, or a C++ class is an anonymous hash. That's because a
hash has an arbitrary number of data fields, each conveniently accessed by
an arbitrary name of your own devising.
then the new derived class can be used as a drop-in replacement for the
old one. This means you should be able to write a program like this:
- use Employee
+ use Employee;
my $empl = Employee->new();
$empl->name("Jason");
$empl->age(23);
