I was surprised a feature was recently added to Getopt::Long (2.35, to be specific) to addresses this very need!
$ perl -MData::Dumper -MGetopt::Long -e'
my %options = ( input => [] );
GetOptions(\%options, "input=s{0,}", "des=s", "r=i")
or die;
print(Dumper(\%options));
' -- -input data modem apps -des "finding files" -r 1000
$VAR1 = {
'r' => 1000,
'input' => [
'data',
'modem',
'apps'
],
'des' => 'finding files'
};
It's marked as experimental.

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.
