I haven't tried this, but I have used cgi scripts that return multiple
instances of the same variable name.  These are ancient scripts that date
well before the perl CGI modules so I'm parsing the input myself.  I create
two perl variables for each name on the input, a scalar that contains the
last setting, and an array containing all entries.  I've hacked getopt.pl
to do the same thing with $opt_? and @opt_? which I did originally for a
front-end to groff where multiple -r options are common.

There are places where having an array of variables is useful.

It is necessary for the welfare of society that genius should be
privileged to utter sedition, to blaspheme, to outrage good taste, to
corrupt the youthful mind, and generally to scandalize one's uncles.
