I suggest reading the man page perlreftut. It clarifies what Perl references are and why they exist. In particular, references exist due to a deficiency in Perl originating in Perl 4 that didn't allow a hash to have anything other than a scalar as a value.
Interesting. I didn't know this page existed. Yet another way that python yields more readable code: Python hashes/dictionaries can contain lists without having to deal with references. In fact, all of the data structures are nestable.
