One more thing, those loops I was telling you about, just using a pair
of brackets, also keep their scope. It's a good way to clean up with
yourself, i.e.
my $foo = 40;
{
my $foo = 50;
print $foo; # prints 50
# garbage collector called on all declarations before here
}
print $foo; # prints 40
Also:
use strict;
use warnings;
Should ALWAYS be at that op of your scripts until you know enough Perl
to know when to bend or break this rule.
