You can include your class into another module of class with using a statement use:
use Employee;
or
use Employee qw( method1 method2 ... methodN );
This is equal following:
BEGIN { require "Employee.pm"; import Employee; }
or
BEGIN { require "Employee.pm"; import Employee qw( method1 method +2 ... methodN ); }
Good like.
