An array slice is just a list. There's nothing to dereference.
For example:
@a = qw(foo bar baz); # @a is an array
@b = @a[0,2]; # @a[0,2] is a slice containing
# 2 elements (foo baz). This list
# is assigned to new array @b
If you have a reference to an array, it would look like this:
$a = [ qw(foo bar baz) ]; # $a is a reference to an array
@b = @$a[0,2]; # slice same 2 elements from
# the array referenced by $a
