No, you are perfectly correct. People should make references. The easiest way to make a reference in Perl is to use a backslash, like this:

\Haskell

However, sometimes there are plenty of resources you want to refer to, but you don't know who authored them! That is the time for an anonymous array constructor.

[ Whenever, Shakespeare, Oroogu ] (Note how efficient Perl is: you only have one reference, even though it points at three different things.)

If what you're talking about is so seriously demented that you suspect the person who made it was not quite sober, you may use a hash reference, which also permits some explanation about what's so insane about it.

    Beatnik => Interestingly bound to English
    Homespring => Promotes (bad) poetry
    ZT => Two dimensional
