You guessed it. You get to use square brackets for an array, and curly braces for an hash, and the syntax stays consistent thru the whole thing, no matter how deeply your data gets nested.
The only time it gets a little 'funky' is when you want to treat your data like a regular array, for example, in a foreach loop. Actually, perldsc lays it all out.
### here we tell perl to treat the scalar as a ref
### to an array.
foreach my $item (@{$chapters}){
print $item->{title};
}
Side note: Data::Dumper is absolutely a plus. Sprinkle it into every script where you use a complex variable, in fact, sprinkle it everywhere. It's very useful.

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).
