Well, it works if the optional arguments are all trailing.
sub lotsaArgs {
my $arg1 = 'default';
$arg1 = shift if @_;
my $arg2 = 'default';
$arg2 = shift if @_;
my $arg3 = 'default';
$arg3 = shift if @_;
my $arg4 = 'default';
$arg4 = shift if @_;
...
}
This would be analogous to default arguments in C++, for instance.
If you want to have named arguments, and only pass some of them, then the hash of default values and
my %args=(%defaults,@_);
as suggested below is obviously better.
But as asked, he seemed to have only one arg to default.

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.
