Copied from http://juerd.nl/site.plp/perladvice:
Here is an incomplete list of things that you will need to understand:
- An object is a reference to a blessed variable.
- A list is not the same as an array.
- There are three main contexts: void context, scalar context
and list context.
- Things are named or anonymous.
- The language is Perl, the implementation is perl. Never write PERL.
- There are different operators for strings and numbers.
- Some operators perform short circuit logical operations, and these
have high and low precedence versions.
- There are lexical variables, package global variables and
package global variables that are always in the main namespace.
- Parameters are expected, arguments are passed.
- An operator is either a unary, binary or ternary operator, or
a list operator.
- A statement consists of one or more expressions.
- You can use alternative delimiters to avoid the leaning toothpick syndrome.
If you understand all this, you have reached at least the level that I think is the absolute minimum required for you to call yourself a "Perl programmer".

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
