print SPECIAL_ARG ordinary_arg_list, with_commas;
This is the only unusual construction that you need to get used to early on. Otherwise arguments are separated by commas.
The syntax may be a little unusual, mostly because it's not used much except with print and printf, but it isn't unique to those functions. It's just the indirect object syntax, new Foo, frobnicate $foo "bar", etc. It's covered in perlobj, and it is generally to be avoided except with builtins.

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).
