Subroutines are global, but they can be given access to scopes that
are not global. Personally I prefer to use anonymous subroutines for
my closures.
#!/usr/bin/perl
use strict;
use warnings;
{
my $i;
sub iter { return $i++ }
}
my $i = 5;
print iter(), "\n";
print iter(), "\n";
print iter(), "\n";
print iter(), "\n";
