perl.j has asked for the wisdom of the Perl Monks concerning the following question:

What do I need to know to start learning references? Where is a good (preferably free) webpage or info source to learn references? Thanks.
--perl.j

      Thanks a lot everyone. Great links. This will really give me a head start. I've been getting into some more advanced Perl and I realized that if I want to do what I want to do, then I can't keep pushing off learning this.

      Yes I know. I just wanted to see if there was anything else and so far there is.

    I started learning Perl from the this link and read couple of the chapters from the book Perl in Nutshell. After that I took an small project and started coding in Perl. I learned a quite a lot during that project. So best way is just learn the basics and start coding it.

      Learning perl is a great stuff, but don't cover references

    Here is an informal but simple way of thinking about it:

    “A reference is a thing (that is to say, a value that you can assign to a variable, etc.) that refers to something else.”

    You see, there are plenty of cases where we would like for a piece of data to be in two places at the same time.   Maybe you’d like to send “a massively complicated data structure” from here to there without copying it.   A reference can refer to anything.

    Dress it up or dress it down ... it is a very simple concept that really is that simple.   Start from there.
