Using Getopt::Long, I would like to have a non-option argument which is unaffected by surrounding options (my options in this case will be mostly switches).

The way I usually handle options is like this:

my %opt =(
 shell => "bash",
   foo => "/some/path",
 input => undef, # yes, i know this doesn't need to be here
);

GetOptions(\%opt,
 'shell=s',
 'foo=s',
 'bip',
 'bar',
 'baz'
);

How can I integrate a non-option argument in this code? Preferably, I would like the argument to be set as $opt{input} so I can act on it one way or another depending on which of the options (bip, bar, baz, or nothing at all) is selected.
