Even in those cases, there are usually clearer solutions...
use Getopt::Long qw( GetOptionsFromArray );
sub do_awesome_things {
GetOptionsFromArray( \@_,
'files=s' => \my @files,
'verbose!' => \my $verbose,
);
warn "Going to process files @files. "
. "Verbose is ".( $verbose ? 'ON' : 'OFF' ).".\n";
}
do_awesome_things -v => -file => 'foo.txt', -file => 'bar.txt';

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
