in reply to Re^2: return more than 1 value
in thread return more than 1 value

Is the Perlish way of assigning an array of values to their equivalent keys. You could, (if you enjoy typing), write
for my $index (0..$#array_of_keys){ $hash{$array_of_keys[$index]}=$array_of_values[$index]; }
In the line you cite there isn't an array @returned_values it is a hash slice. take a look at the perldata man page for further, better presented, info

print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."
