If sort returned the array the code would look even simpler. Don't really understand why this function is by reference. Anyway I was thinking about the size of the DB more than anything else.

Also the scrabble thing needs to output a group of words for each intersection. So 7 tiles + a, through to z, and then we could find places on the board the letters could be useful.
