In addition to japhy's excellent answer, I'd like to just point out what this is doing for anyone who might not quite understand why this works as it does.

(my_func()) forces the output of this function into list context as well as groups it for the [5] we're about to append. Now that [5] takes a slice of the list.

Here's a simple example
sub foo { return qw(a b c d) } ( foo() )[1,3]; # Is the same as: ('a', 'b', 'c', 'd')[1,3]; # And effectively the same as @a = foo(); @a[1,3];
You can read more about slicing in the book Effective Perl Programming (a *must* read =)
