No, a hash is a 1 to 1 relationship between key and value.
However, by using an anonymous array as the value you can
accomodate several values.
E.g.
%hash('james' => ['1', '2'],
'kelty' => '3',
'biran' => '4');
When accessing the keys you check for an array ref, if so
you have multiple values. More memory and you can just
create each value as an array.
