I think the useful point that somehow got buried in the sand along with the
ostrich was that security is a running battle. You *must* take every
opportunity to plug everything that could conceivably be a security hole,
even if it depends upon some other layer of security being broken
first.

So it's basically suggesting you either use the object oriented interface
- if available - ( Foo->foo() ) or you use fully qualified function names
( Foo::foo() ). Also, as a rule of thumb, to avoid importing functions,
you can use require instead of use as this usually even avoids importing
default exports.

Learning Perl is the quintessential tutorial for the Perl programming
language. The third edition has not only been
is $city from the hash %state. Now we can
put it all together:
foreach my $person (@{$state{$city}{$street}{people}}) means:
Set the lexical $person in turn to each of the members of the array
referenced by the element with key 'people' in the hash referenced by the
elemen
hash{$key}
