I was just trying direction to see what kind of outputs it gives on a horizontal hexagonal board. This is the code

set north direction g7 g8;
set northeast direction g7 h7;
set northwest direction g7 f8;
set south direction g7 g6;
set southeast direction g7 h6;
set southwest direction g7 f7;
print #north #northeast #northwest #south #southeast #southwest;

and the output was

Array
(
    [0] => w
    [1] => se
    [2] => s
    [3] => nw
    [4] => e
    [5] => #north
)

What is happening with #north?
