Non-standard? Getopt::Long supports this with no problems. Here's a snippet from the POD:

Example of using variable references: 

   $ret = GetOptions ('foo=s', \$foo, 'bar=i', 'ar=s', \@ar);

With command line options ``-foo blech -bar 24 -ar xx -ar yy'' this wi
+ll result in: 


   $foo = 'blech'
   $opt_bar = 24
   @ar = ('xx','yy')

Looks to me like Getopt should have no problem with the original question. gaspodethewonderdog just needs to change the variable into a reference.

Update: MeowChow is right - the example does use the -ar multiple times instead of just once. However, I do know that it can be done, since I have a working example.
