Hello Leitz,

In looking through this thread, one thing that I don’t seem to have seen mentioned is context, which is a very important part of Perl, and a key way in which Perl differs from most other procedural languages (pace the node immediately preceeding this one). Since your goal is to begin with the basics, your learning plan should include Context in Perl at an early stage, perhaps immediately following Data types and sigils. Here are a couple of references to help you get started:

• Scalar and List context in Perl, the size of an array by Gábor Szabó
• Context tutorial by kyle

When you come to study data structures (see perldsc), another concept you will need to learn is autovivification, which is a very useful Perl feature but also a source of perennial consternation to programmers who aren’t expecting it! The classic reference is:

• http://www.sysarch.com/Perl/autoviv.txt by Uri Guttman

Hope that helps,
