As you say, one good reason for references is to build complex data structures. Another is to pass arrays and hashes into and out of subroutines. And, of course, all of Perl's OO capability is based on references.

Many people find perlref to be a bit dry on first reading. That's why Dominus wrote perlreftut. You might find that makes a bit more sense to you.
