Surprised no one has mentioned it, but the complete foundation of Object Oriented Perl is based on the ability to bless a referent into a particular namespace. So obviously once/if you get into OOP references play a major role.
Along these lines is the ability to pass multiple different types of data into and out of subroutines, so that a sub may perform and return different types of actions and data based on what it was given.
