[Omaha.pm] Getopt::Long and opt_ variables

[Dave Thacker]

In the second edition camel (on page 448), it says that" "If no linkage is 
explicitly specified and no hash ref is passed, GetOptions() will put the 
value of in a global variable named after the option preceded by opt_..." 
Is this automagically done? This example doesn't seen to work .

#!/usr/bin/perl -w

use strict;
use Getopt::Long;
my $opt_place;

&GetOptions("place=s");

print "Hello! $opt_place\n";

value in concatenation (.) or string at ./test2.pl line 9. Hello!
