\$animal --> create a reference to $animal, which contains 'Dog'
$sound --> assigned the reference to the variable $animal, which contains
'Dog'.
$$sound --> dereferences the reference to get the actual data stored,
which is 'Dog'
$bark --> assigned to the value referenced by $sound when $sound is
dereferenced ($$sound), which is 'Dog'.
Dig out your handy perldoc tool and read perlref and perlreftut.
