Somehow the \ in this case doesn't do what I need.
Correct. The following:
\( ... )
takes a reference of every item in the list, without flattening it first.
See the following as an example:
use Data::Dumper;
my $scalar = 'string';
my @array = ( 1,2,3 );
my %hash = ( a => 1, b => 2 );
print Dumper \( $scalar, @array, %hash );
This is also a useful trick for getting a reference to a scalar when your editor's syntax coloring (eg, BBEdit) thinks you're escaping a quote:
my $var = \('string');

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).
