As long as you don't need to initialise the array, you should be fine if you simply
omit the parentheses. For example
#!/usr/bin/perl
use Getopt::Long;
GetOptions(
'thing=s' => \(my $thing = ''),
'flag' => \(my $flag = 0),
'array=s' => \my @array, # no parens
# ...
) or die 'options';
print "\@array: @array\n";
when called as
$ ./646480.pl -a foo -a bar -a baz
would print as expected
@array: foo bar baz

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).
