Brethren,
How do I pull out the n'th value when a function returns a list, without using an intermediate array variable? E.g. the following works, but by introducing the clutter of @temp;
use strict;
sub dirs{qw(NORTH SOUTH EAST WEST)}
my(@temp) = dirs();
my($horaceGreeleyDir) = $temp[3];
but the following attempts don't
my($horaceGreeleyDir) = dirs()[3];
my($horaceGreeleyDir) = @{dirs()}[3];
my($horaceGreeleyDir) = ${dirs()}[3];
my($horaceGreeleyDir) =()[3] = dirs();
This works, but is looks worse than the original:
(undef, undef, undef, my $horaceGreeleyDir) = dirs();
Suggestions?

meta-question: on what should I have searched to answer this question myself?
