Sorry about this nitpick, that too a late one at that. In the above
code, you've created a hash variable but are assigning it a hash
reference as value. The %contact_details variable will now have the
stringified hash set as key and value being undef.  Like this:

> $ perl -MData::Dumper -e 'my %x = { key => q(value) }; print Dumper \%x'
> $VAR1 = {
>           'HASH(0x132e998)' => undef

The correct way of doing it... well, TIMTOWTDI, so:

You could either only talk in terms of references:

my $contact_details = { key => value }

or in terms of hashes

my %contact_details = ( key => value )
