Amazing! It is really true that if you want to achieve results, you should throw a competition!
Here are the shortest ones so far: (29)
map{$a=$_;map$a.$_,1..8}a..h; # by runrig
map{$r=$_;map$_.$r,a..h}1..8; # by Anonymous
Runrig's solution could be reduced to 
map{map{$_}$_.1..$_.8}a..h; #27, but unfortunately it's the wrong orde
+r.
