“When I referred to Perl references I was, for the most
part, laying the foundation for easily understanding the entire
concept. If you attack the problem semantically, and try not to
think of it as a bunch of backslashes and arrows and symbols, it
makes perfect sense 🙂 If I’m wrong, and this post leaves you
reeling in confusion and pain, please let me know so I’ll stop
being so cavalier with my prose 🙂“So, let’s take a look at Perl references and how they can be
used, most basically, in a step-by-step fashion; from the simplest
of beginnings to the not-so-complex middle (We’ll leave references
to hashes of arrays of references to other hashes for some other
day 😉“For all of these examples, we’ll use command line examples, so
you can cut and paste them to try them out, rather than pretend
that we’re inside a Perl script.”
