$string could be defined inside the BEGIN block, or the BEGIN block could be left out altogether. I only included it in my example out of sheer reflex. :-) Here's another example that might be more useful:

my $options;
my $string = <<'HERE';

    -one <one:i>    First parameter
    
HERE

require Getopt::Declare;
import Getopt::Declare $string => $options;
