Dear Monks,

I have a Hash-of-hash, and each of the child-hashes contains a value that I am interested in accessing just once. This value is the same for all of the child hashes.

I have found two ways to access the value, but wonder if there is a better way?? 

my $hoh = {
    apples   => { source => 'uk', colour => 'red', },
    pears    => { source => 'uk', colour => 'green', },
    bananas  => { source => 'uk', colour => 'yellow', },
  };

# naff: get source, using var in a list assignment
my ( $any ) = values %$hoh;
print "source: ", $any->{source}, "\n";

# naff: create an anonymouse array and access element[0]
print "source: ", ${[values %$hoh]}[0]{source}, "\n";
