my @fools = qw(jester clown motley);
my $fools = \@fools;
The $fools variable now contains a reference to the @fools array. You can copy the values to
another array by prepending it with the @ sign (the array sigil).
my @copy_of_fools = @$fools;
To access individual elements of the $fools array reference, you use the same syntax as you would
to access the original array, but you use the dereferencing operator, ->, between the array name and
the square brackets.
