Hmmm, tye's solution provides insight to another: 
# You might already have this type of function available.  
# If not, it's needed for the next part:
sub same_coord
{
   my ($aref, $bref) = @_;
   my @acoord = @$aref;
   my @bcoord = @$bref;
   return 0 if ( scalar @acoord != scalar @bcoord );
   foreach my $i ( 0..$#accord ) {
      return 0 if ( $acoord[$i] != $bcoord[$i] );
   }
   return 1;
}

sub get_neighbors {
   my @coord = @_;
   my @n = ( [] );
   foreach my $i ( 0..$#coord ) {
      @n = map { @left = @$_; 
                 map { [ @left, $_ ] } ( $coord[$i]-1..$coord[$i]+1)
               } @n;

   }
   @n = grep { !same_coord( \@coord, $_ ) } @n;

   return @n;
}

It's not what you know, but knowing how to find it if you don't know that's important
