You can by sharing variables. Somehow I didn't manage to do with simply sharing a variable and localizing it, but I'm quite sure it can be done.
This is my workaround for now:
#!/usr/bin/perl
use Safe;
use IO::File;
our @args;
my $code =<<'END';
my @args = pass_options();
return "Arguments: @args\n";
END
my $compartment = Safe->new;
sub pass_options { @args };
$compartment->share('&pass_options');
$safe = sub { local @args = @_; $compartment->reval($code) || die $@};
print $safe->(1, 2, 3);
__END__
Arguments: 123
This takes the sideway of sharing a sub that returns the arguments. Not ideal, but at least it works.

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).
